Before You Clean Your Salt Cell… Read This Treatment guide First
Why Most Salt Cells Fail Early in Florida
- High calcium = scale builds fast
Heat + evaporation = worse conditions - Over-cleaning with acid = silent damage
- Most failures aren’t defects—they’re preventable
Salt Cell Cleaning Checklist
Cleaning a salt cell should only be done when visible scale is present, as unnecessary acid washing shortens the life of the cell. Follow this step-by-step process to ensure effective cleaning without damaging the equipment.
1. Preparation & Safety
- Gather required tools: You will need muriatic acid, clean water, a plastic bucket (never metal), a cell cleaning stand or cap, and safety gear including gloves and eye protection.
- Shut down the system: Turn off the pool pump and the salt system power, then relieve pressure if necessary.
2. Removal & Inspection
- Remove the cell: Carefully disconnect the unions and inspect the O-rings for wear, replacing them if they appear damaged.
- Perform a visual inspection: Look inside at the plates. If you only see a light dusting of debris, do not acid clean the cell. Proceed only if you see moderate to heavy white, crusty scale.
3. Mechanical Cleaning (Try This First)
- Use water pressure: Use a garden hose to try and flush out loose debris.
- Use plastic tools only: If needed, use a plastic tool to gently dislodge scale, but never use metal to scrape the plates.
- Stop if successful: If the plates are clean after this step, reinstall the cell and skip the acid wash to preserve its lifespan.
4. Acid Cleaning (Only if Necessary)
- Mix the solution: Use a ratio of 4 parts water to 1 part muriatic acid.
- Safety Rule: Always add the acid to the water, never the reverse.
- Soak the cell: Cap one end of the cell and fill it with the solution.
- Monitor the time: Let the cell sit for 5–10 minutes MAX. You should see bubbling as the scale dissolves.
- Avoid over-soaking: Never leave the acid in the cell longer than 10 minutes, as it wears down the protective plate coating.
5. Rinse & Reinstall
- Flush thoroughly: Rinse the cell with plenty of clean water to ensure no acid remains.
- Reinstall: Replace the cell using lubricated O-rings.
- Restart: Turn the system back on and verify proper flow and chlorine production.
Pro-Tips for Longevity
- Manage water chemistry: If you are cleaning your cell more than 2–3 times per year, you likely have a chemistry issue, such as high pH or calcium hardness.
- Target LSI: Maintain a slightly negative LSI (-0.1 to -0.3) to prevent scale from forming on the plates in the first place.
- Avoid “Just Because” cleaning: Only clean when you see scale or receive a “Check Cell” light; cleaning every month “just in case” will destroy the cell prematurely.
Green Pool To Clear and Blue Checklist Treatment Guide
Transform your backyard swamp back into a summer oasis
Our comprehensive “Green to Clean” protocol.
When your pool shifts from sparkling blue to a murky, moderate-to-heavy green, it’s a sign that algae has taken hold and a simple skimming won’t cut it.
This transformation requires more than just luck; it demands a strategic “Attack Mode” that begins with clearing out debris, ensuring your pump has perfect circulation, and precisely balancing your water’s pH to prepare for a powerful triple dose of shock
This checklist is based on a standard Day-by-Day Green to Clean procedure for treating moderate to heavy green algae. Note that the chemical dosages listed below are specifically calculated for a 15,000-gallon pool.
1. Preparation (Before Day 1)
- Turn off the pool heater.
- Top off the water level to ensure it is at the proper height for circulation.
- Clean out all debris using a leaf rake and skimmer, or vacuuming to waste if necessary.
- Brush the pool thoroughly to loosen algae from the surfaces.
- Ensure good circulation by checking the pump and return flow.
2. Day 1: Attack Mode
- Test and adjust the pH to between 7.2 and 7.4.
- Add muriatic acid (approximately 2.5 quarts) if the pH is currently high (above 7.6). Need to get pH down to a 6.9 -7.1
- Apply a triple dose of shock using either 2 gallons of liquid chlorine (12.5%) or 1-2.5 lbs of Cal-Hypo (73%), broadcasting it across the surface in the evening.
- Add Algaecide (Non-Copper, Polyquat 60) at a rate of 34 oz (1 oz per 1,000 gallons).
- Run the pump 24/7 and brush the pool again.
Day 2: Maintain Kill Zone
- Test the Free Chlorine levels.
Re-shock the pool if Free Chlorine is below 5 ppm using 3 gallons of liquid chlorine or 3.5 lbs of Cal-Hypo. - Backwash or clean the filter to remove dead algae.
- Brush the pool again.
Day 3: Clear the Cloud
- Assess water clarity:
If the water is gray or blue but cloudy, add 17 oz of clarifier (½ oz per 1,000 gallons). - If the water is still greenish or heavily cloudy, add 17 oz of flocculant and shut off the pump overnight.
On Day 4 (if using flocculant): Vacuum to waste slowly to remove the settled debris from the floor.
Day 4–5: Polish & Balance
- Test and adjust chemicals to reach these target ranges:
pH: 7.4–7.6.
Alkalinity: 80–120 ppm.
CYA (Stabilizer): 30–50 ppm.
Chlorine: 2–4 ppm. - Backwash the filter again if necessary.
- Add a phosphate remover as an optional but recommended as the final step.
Ongoing Maintenance Tips
To prevent the algae from returning, you should brush and shock the pool weekly, keep chlorine levels between 2–4 ppm, and run the pump for 10–12 hours per day.
Black Algae Won’t Go Away? Here’s the Exact Treatment Guide Pros Use to Kill It for Good
The Hidden Pool Problem That Survives Chlorine
Black algae is one of the toughest problems a pool owner can face because it doesn’t just sit on the surface—it roots deep into the plaster, forming a protective layer that shields it from normal chlorine levels.
In Florida pools, with intense sun, warm water, and heavy bather load, chlorine gets used up faster, giving black algae the perfect chance to survive and spread.
That’s why simple brushing or shocking rarely works—you have to break through its protective barrier and treat it at the source, or it will keep coming back.
Black Algae Removal Checklist
Black algae is notoriously difficult to eradicate because it roots deeply into pool surfaces and protects itself with a waxy outer layer. Follow this detailed checklist to systematically eliminate it from your pool.
1. Initial Filter Cleaning & Water Prep
- Clean the filter: If the problem is small, backwash or rinse your filter; if extensive, use a filter cleaner or completely replace the filter medium/cartridge to ensure no spores remain.
- Balance the water: Adjust your levels to ensure the shock treatment is effective.
- Alkalinity: 100–150 ppm (125 ppm is ideal).
- pH: 7.4–7.6.
- Chlorine: 1–3 ppm.
2. Aggressive Mechanical Cleaning
- Brush with the right tools: Use a stainless-steel-bristled brush for concrete or plaster pools to dig into crevices. For fiberglass or vinyl liners, use a nylon-bristled brush and significantly more “elbow grease”.
- Scrub specific spots: For stubborn spots that won’t budge, use a putty knife, pumice stone, or a hand-held wire brush.
- Use the Chlorine Tablet Trick: Break a 3-inch chlorine tablet in half and scrub the black algae directly with the broken edge while wearing protective gloves. For hard-to-reach areas, use a tablet holder attached to a telescoping pole.
- Brush a second time: Once you have loosened the algae from the surfaces, brush the entire pool again to get the particles into the water.
3. The “Kill Zone” Treatment
- Quadruple Shock: Apply four times the manufacturer’s recommended dose of pool shock to ensure the high chlorine levels reach the now-exposed algae.
- Sanitize your gear: Place all maintenance equipment (brushes, poles, skimmers) in the shallow end of the pool during the shocking process to kill any lingering spores on the tools.
- Run the pump for 24 hours: This circulates the high dose of chlorine throughout the entire system.
- Brush repeatedly: During this 24-hour circulation period, brush the pool surfaces at least 2 to 4 more times to ensure the chlorine reaches the roots.
4. Follow-Up & Final Balancing
- Clean the filter again: Perform a second cleaning using a filter cleaner to remove the dead algae particles trapped during the shock process.
- Secondary Shock (if needed): If black algae remnants are still visible, perform a double dose of shock and run the pump for another 24 hours.
- Final Brush and Test: Brush the surfaces one last time and then test the water to bring all chemical levels back to their ideal ranges.
5. Long-Term Prevention
- Sanitize outside items: Always wash swimsuits and scrub pool toys with a bleach-and-water solution (1 tablespoon of bleach per gallon) if they have been used in natural bodies of water like lakes or oceans.
- Maintain strict chemistry: Keep alkalinity, pH, and sanitizer in the recommended ranges at all times.
- Regular maintenance: Run your pump 8 to 12 hours daily, vacuum and brush regularly, and shock the pool at least once a week.
- Monitor for stragglers: Watch for small spots over the next few weeks; if any reappear, immediately scrub them with a broken chlorine tablet and apply a normal dose of shock.
The Number 1 Hidden Cause of Algae in Your Pool—And How to Fix It Treatment
Lakeland, Plant City Lake Wales areas has one of the highest concentrations of phosphates in the country.
If algae keeps coming back?
No matter how much you shock you add the algae returns, then phosphates are usually the hidden driver.
They feed algae and are constantly introduced in Florida through pollen, runoff, and fill water. As levels rise, chlorine gets used up faster fighting organics instead of sanitizing—so it never holds.
Remove the phosphates, and you cut off algae’s food source, stabilize chlorine, and keep your water clear with less effort and cost.
Follow this detailed checklist to effectively lower phosphate levels in your residential pool.
Step 1:
- Test Your Phosphate Levels
Use a reliable test kit: Liquid or digital kits are preferred for accuracy. - Sample correctly: Draw water from elbow depth, not the surface.
- Evaluate your results:0–100 ppb: Ideal.
- 100–300 ppb: Manageable.
- 300–1000 ppb: Elevated; treatment is recommended.
- 1000+ ppb: High; expect multiple treatments.
Step 2:
- Inspect and Prepare the Pool
Check for Algae: Critical Rule: Never rely on a phosphate remover to fix an active algae bloom. If algae is present, you must brush, shock, and clear it first before starting the removal process. - Record Baseline Pressure: Take note of your current filter pressure.
Step 3:
- Balance Water Chemistry
Phosphate removers (lanthanum-based) work most effectively when the water is balanced. - Ensure your levels are within these ranges:
- Free Chlorine: 3–5 ppm.
pH: 7.2–7.6. - Alkalinity: 80–120 ppm.
- Free Chlorine: 3–5 ppm.
Step 4:
- Clean the Filter (Non-Negotiable)
Phosphate removers create fine particulates that the filter must be able to capture. A dirty filter will yield poor results.- Cartridge filters: Fully rinse and deep clean.
- Sand/DE filters: Backwash thoroughly.
Step 5:
- Apply the Phosphate Remover
Calculate pool volume accurately: Do not guess, as overdosing can cause excessive clouding. - Dose according to the label: Pour slowly into the skimmer or directly into the pool based on the specific product instructions.
- Run the pump continuously: Keep the system circulating for 24–48 hours.
- Step 6: Monitor and Manage the Reaction
Expect temporary cloudiness: This is a normal reaction as the phosphates are pulled out of the solution. - Do not add clarifier immediately; let the filter do its work.
Monitor filter pressure: - Check the gauge every 6–12 hours. Because the remover is binding phosphates into particles, your filter will clog faster.
- Clean the filter again: Backwash or clean the filter whenever the pressure rises 8–10 PSI above the baseline. If you fail to clean the filter during this stage, the phosphates may remain in the system.
Step 7:
- Final Testing and Maintenance
Retest: Wait 48 hours after the treatment is complete. If levels are still above 300 ppb, repeat the treatment. - Restore Chlorine: Bring chlorine levels back to the normal 3–5 ppm range.
- Prevent return: To keep levels low, rinse deck debris before storms, limit fertilizer runoff, and clean skimmer baskets regularly.
Common Mistakes to Avoid
- Treating while algae is active: This is the most common cause of failure.
- Skipping filter cleanings: The filter is what actually removes the bound phosphates from your pool.
- Expecting instant results: Phosphate removal is a process that takes several days of filtration, not an instant shock treatment.
The 28-Day Countdown: Protecting Your New Pool Finish from Day One
The first 28 days of your pool’s life are the most critical period for its long-term health, as 86% of the cement in a new plaster finish cures during this brief window.
Following these specific startup procedures is essential for protecting your investment and significantly prolonging the lifespan of the pool finish.
By committing to this 28-day regimen of diligent water testing, twice-daily brushing to remove plaster dust, and precise chemical balancing, you ensure a long-lasting, beautiful surface.
Neglecting these steps or failing to maintain the proper Langelier Saturation Index (LSI) can lead to irreversible damage, including:
- leaching,
- etching,
- scaling,
- permanent discoloration.
Ultimately, strictly adhering to these guidelines is the best way to maintain the gorgeous appearance of your new pool while ensuring your finish remains within its warranty requirements.

- sequestering agents,
- chlorine,
- stabilizer.
2. Critical Rules & Restrictions
- Safety First: NEVER mix water into chemicals; always add chemicals to a bucket of water first.
- No “Wheeled” Equipment: Do not use robotic cleaners, automatic pool cleaners, or wheeled vacuums for the first 28 days.
- No Salt: Wait at least 28 days (and up to 6 weeks) before adding salt or starting a salt-water generator.
- No Heat: Do not use the pool heater until all plaster dust has been removed, typically between Day 4 and Day 10.
- No Shocking: Do not “shock” the pool for the first 30 days.
- No Swimming: Do not allow people or pets in the pool until the water is balanced and sanitized.
3. The Fill Day
- Test Fill Water: Test your source water for pH, alkalinity, calcium hardness, and metals before filling.
- Protect the Finish: Wrap a clean rag around the end of the hose or attach a float to prevent the hose from directly touching and damaging the new plaster.
- Continuous Fill: Fill the pool as rapidly as possible to the middle of the skimmer. Do not stop the water during the process, or it will leave a permanent “bowl ring” line on the finish.
- Start Filtration: Turn on the filtration system immediately once the pool is full.
4. Day 1: Initial Balancing
- Test and Record: Test the water and record results in an LSI tracking app.
Adjust Total Alkalinity: Use pre-diluted muriatic acid or sodium bicarbonate to reach 80 ppm. - Adjust pH: Reduce pH to between 7.2 and 7.6 using pre-diluted muriatic acid.
Brush Twice Daily: Brush the entire pool from top to bottom, shallow end to deep end, to remove plaster dust. - Add Sequestering Agent: Use a high-quality sequestering agent to prevent metal staining.
- Circulate: Run the filtration system continuously for at least 72 hours.
5. Days 2–3: Hardness & Sanitizer
Day 2 – Calcium Hardness:
Once pH and alkalinity are set, adjust calcium hardness to a minimum of 150 ppm.
Day 3 – Chlorine:
You may now add pre-diluted chlorine to achieve a level of 1.5 to 3.0 ppm.
Ongoing Brushing: Continue brushing the entire surface at least twice daily.
6.
Days 4–28: The Curing Phase:
- Daily Testing: Monitor pH, Alkalinity, and Calcium Hardness daily for the first 14 days.
- Adjust Calcium Slowly: Gradually increase calcium levels, but do not exceed 200 ppm during this period.
- Add Stabilizer: Adjust cyanuric acid (stabilizer) to between 30 and 50 ppm.
Vacuuming: On Day 7, you may use a brush-style pool vacuum (no wheels) to remove any remaining plaster dust.
Post-28 Day Maintenance
- LSI Targets: Once the initial startup is complete, maintain your LSI between 0.0 and +0.3 for daily maintenance.
- Monitor Closely: Disregarding LSI parameters can lead to leaching, etching, or scaling of your new finish.
