A single June thunderstorm can dump enough rainwater to dilute your salt, crash your chlorine, and wash a season’s worth of organic debris into your pool overnight.
If you run a salt pool on Hayward OmniLogic, Pentair IntelliCenter, or Jandy iAquaLink, your automation panel already has a one-tap weapon for this exact moment: super-chlorination, also called Boost mode. This guide walks you through the full storm-recovery sequence — clean, balance, then boost — and shows you the precise menu path to activate super-chlorination on all three platforms, so your water is clear and safe again before the next pool party.

What Super-Chlorination Actually Does
On a salt pool, your chlorine isn’t poured from a jug — it’s manufactured on demand by the salt cell as water passes through it. During normal operation, your automation system runs that cell at a percentage of its capacity (say, 40% or 60%) to hold a steady free chlorine level. Super-chlorination overrides that percentage and forces the cell to 100% output for a fixed window — by default 24 hours on all three major platforms.
That burst of extra chlorine does the work that a heavy June storm demands: it oxidizes the organic load rainwater drags in, burns off the combined chlorine (chloramines) that cause the harsh “chlorine smell,” and rebuilds a sanitizer reserve that dilution wiped out. Think of it as flooring the accelerator on your existing chlorine factory rather than dumping a bag of shock.
Super-chlorination (Boost mode) sets your salt cell to 100% output for 24 hours by default — adjustable from 1 to 96 hours on Hayward OmniLogic. It is a maintenance booster, not a cure for an active green algae bloom.
The Storm Recovery Sequence: Clean, Balance, Then Boost
The single biggest mistake after a storm is jumping straight to the Boost button. Super-chlorination is only effective when the water is already balanced and free of large debris. Hit boost on a leaf-choked, chemically-unbalanced pool and you’ll waste most of that chlorine oxidizing twigs and bugs instead of the microscopic contaminants that actually matter.
Follow this order every time. Each step sets up the next:
Lower the water level if needed, empty baskets, rake out organic debris, and audit your filter pressure. Chlorine spent on leaves is chlorine wasted.
Adjust Total Alkalinity, then pH, then Cyanuric Acid — in that order. Chlorine loses up to 50% of its potency when pH climbs above 8.0, so balancing first protects every dollar of sanitizer you’re about to make.
Only now do you tap Boost / SC on your automation panel — and ideally do it at dusk so the sun doesn’t burn off your fresh chlorine before it works.
Before You Touch the Panel: The Prep Checklist
Here’s the groundwork to lay before super-chlorination earns its keep.
- Lower the water level. If rain pushed the water above mid-skimmer, turn your multiport filter valve to “WASTE” or “BACKWASH” and drain until the level is centered on the skimmer mouth. Skimmers can’t pull surface debris when they’re drowned.
- Remove physical debris. Empty the skimmer and pump baskets, then use a leaf rake to pull large organic matter off the floor and surface.
- Audit your filter. Check the pressure gauge. If it reads 8–10 PSI higher than your clean starting pressure, backwash (sand/DE) or pull and rinse the cartridges before boosting — a clogged filter starves the pump that the boost cycle relies on.
- Balance the chemistry — in order. Use a reliable test kit such as the Taylor K-2006. Each adjustment affects the next, so sequence matters.
Target Ranges Before You Boost
| Parameter | Target Range | Why It Matters |
|---|---|---|
| Total Alkalinity | 80–120 ppm | Buffers pH; balance this first. |
| pH | 7.4–7.6 | Above 7.8 chlorine fades fast; above 8.0 you lose ~50%. |
| Cyanuric Acid | 30–50 ppm | Stabilizer that shields chlorine from UV. |
| Salt | 2700–3400 ppm | Rain can dilute salinity by 200–500 ppm. |
| Free Chlorine (post-boost target) | 1.0–4.0 ppm to swim | Don’t re-enter until it drops back into range. |
Unstabilized chlorine degrades in direct sunlight at roughly 1 ppm per hour. Always start your boost cycle at dusk or after dark so the cell’s output goes to work on contaminants instead of being burned off by UV.
Storm cleanup starts with getting the leaves out. This deep-bag leaf rake clears floor and surface debris fast — so your boost cycle attacks contaminants, not foliage. Backed by our 490 Promise.
Activating Boost by Brand: OmniLogic, IntelliCenter & iAquaLink
All three platforms reach the same destination — cell at 100% for 24 hours — but the menu path and the on-screen confirmation differ. Find your system below.
Filter Pressure: Normal vs. Danger During Recovery
Storm debris clogs filters fast, and a clogged filter under a 24-hour boost cycle is a recipe for a stressed pump or a ruptured tank. Keep an eye on the gauge throughout recovery.
| Reading | What It Means | Action |
|---|---|---|
| 8–15 PSI | Typical clean baseline for most residential setups. | Normal — proceed. |
| +8–10 PSI over clean (Hayward/Pentair) +10–12 PSI (Jandy) | Filter is loaded. | Backwash or clean cartridges before boosting. |
| 40–50 PSI | Dangerous overpressure; clamshell filters can rupture. | Shut the system off immediately. |
| Sudden drop | Clogged skimmer basket or pump impeller — flow is choked. | Clear the blockage; the cell won’t fire without flow. |
A salt cell needs adequate water flow to operate. If a clogged basket or impeller drops your flow during the boost window, the chlorinator simply won’t fire — you’ll think you’re super-chlorinating while nothing is actually happening. Always confirm flow before walking away.
When the Cell Can’t Keep Up: Shocking From an Alternate Source
A salt cell is built to maintain chlorine, not to drag a green swamp back to clarity. For heavy storm recovery — or anytime the water has tipped toward an algae bloom — manuals recommend “shocking from an alternate source” rather than leaning on the cell alone. Running the cell flat-out to fight a major bloom puts a heavy demand on it and significantly shortens its lifespan.
Use these dosing guidelines alongside (or instead of) the boost cycle when conditions are severe:
- Clear but depleted water: 1 lb of pool shock per 10,000 gallons.
- Green water: 3–5 lbs per 10,000 gallons to reach breakpoint chlorination (typically 10.0 ppm or higher).
- Salt was diluted: roughly 250 lbs of salt per 10,000 gallons rebuilds a 3000 ppm baseline from zero — you’ll need far less to top up a 200–500 ppm rain dilution.
Reach for liquid chlorine or cal-hypo as your alternate source, and again — add it at dusk for maximum staying power.
Mistakes That Wreck Equipment
Super-chlorination is safe and simple — until a few avoidable errors turn a 24-hour boost into a repair bill.
- Leaving the cleaner in the pool. Robotic and suction cleaners left in the water during Boost mode suffer premature wear and corrosion to plastic shells, wheels, and metal parts. Pull the cleaner before you boost.
- Leaving the solar cover on. High chlorine concentrations rapidly attack the plasticizers in solar blankets, leaving them rigid, brittle, and prone to failure. Remove the cover for the duration.
- Using the salt cell to fight active algae. As above — this overworks the cell and shortens its life. Shock from an alternate source instead.
- Misusing dry acid. Adding dry acid (sodium bisulfate) to lower pH in high-heat or arid regions can build up sulfate by-products that permanently damage the cell plates.
- Skipping the balance step. Boost a pool sitting above pH 8.0 and as much as 50% of the chlorine’s potency is wasted — you pay for output you never get.
The Never-Do List (Safety First)
These aren’t preferences — they’re the lines that prevent fires, explosions, and chemical burns.
- Never shock through the skimmer. Pouring granular shock into the skimmer — especially with an inline chlorinator present — can cause a deadly gas expansion and explosion that destroys equipment.
- Never mix chlorine types. Combining different forms (e.g., cal-hypo and trichlor) can trigger violent reactions, fires, or explosions.
- Never swim during Boost mode. With chlorine above 5.0–10.0 ppm, the water is highly corrosive and can cause skin and eye damage. Wait until free chlorine returns to 1.0–4.0 ppm.
- Never skip PPE. Wear safety goggles, chemical-resistant gloves, and a face mask whenever you handle concentrated chemicals.
How Often, and the Signs You Need It Now
As routine insurance, run Boost mode weekly during peak season. Beyond the calendar, activate it immediately when you see any of these red flags:
- Cloudy or hazy water — often the first stage of an algae bloom or a sign of insufficient sanitizer.
- Free chlorine below 1.0 ppm — the “danger zone” where bacteria and algae take hold.
- A strong chlorine smell or eye irritation — counterintuitively, this means combined chlorine (chloramines) above 0.3 ppm needs oxidizing, not less chlorine.
- Environmental triggers — heavy rainstorms, a packed pool party, or any big change in water level.
Delay matters. When the signs are present and you wait, algae and pathogens multiply fast — a slightly hazy pool can become a green swamp within hours in hot weather, and low sanitizer levels raise the risk of recreational water illnesses like E. coli and Giardia.
Seasonal & Pool-Size Settings
Your boost and baseline output settings should flex with the season and your pool’s volume.
- June heat spike: Water above 85°F plus storm-borne nitrogen fuels rapid algae growth. You may need to push pump runtimes to 12–18 hours to hold 2.0–4.0 ppm free chlorine.
- Winter cutoff: Most cells automatically shut down between 50°F and 52°F to protect the plates — boosting in cold water simply won’t generate chlorine.
- Pool under 15,000 gallons: set initial cell output around 40%.
- Pool 25,000–40,000 gallons: set initial cell output around 60%.
Salt Level Indicators by Brand
| Brand | How It Reports Salt |
|---|---|
| Hayward | Displays “Average Salt” and “Instant Salt”; standard range 2700–3400 ppm. |
| Pentair | Green = good, flashing green = high (>4500 ppm), red = low (<2600 ppm). |
| Jandy | Shows “JA” when the RS system is in control and “bo” during boost. |
Hayward cells (AquaRite, AquaTrol, OmniLogic TurboCell) flash an “Inspect Cell” reminder roughly every 500 hours of operation — your cue to check for calcium scale. Pentair’s IntelliChlor instead tracks a built-in usage meter toward its ~10,000-hour service life. Either way, heavy boosting accelerates run hours, so storm season brings these reminders around faster.

Warranty Traps to Avoid
Doing this wrong can cost you more than a repair — it can void the coverage that would have paid for that repair.
- Chemistry neglect. Operating with a Saturation Index (LSI) outside the -0.5 to +0.5 window can cause permanent scaling or corrosion that voids the cell warranty.
- Online-purchase exclusions. Several brands — Jandy/Fluidra in particular — offer no warranty on products bought online; they must be installed by a licensed professional to be valid. Check before you buy.
- Dry acid in hot climates. Pentair and Hayward manuals explicitly discourage dry acid (sodium bisulfate) in high-heat/arid regions because the resulting sulfate buildup damages cell plates — and that damage isn’t covered.
Your Storm-Recovery Supplies Checklist
Keep these on hand so a June storm never catches you flat-footed:
- ✅ Reliable test kit — Taylor K-2006 or Leslie’s AccuBlue Home for 10-point analysis.
- ✅ Alternate sanitizer — liquid chlorine or cal-hypo for breakpoint shocking when the cell can’t keep up.
- ✅ Heavy-duty leaf rake with a nylon mesh bag.
- ✅ The right brush — stainless steel for plaster, nylon for vinyl.
- ✅ A sturdy telescoping pole to drive every tool.
- ✅ Phosphate remover — levels spike after rain.
- ✅ Clarifier or flocculant to clump fine suspended silt.
- ✅ PPE — goggles, chemical-resistant gloves, face mask.
Brushing walls and floor before you boost knocks loose the algae spores chlorine needs to reach. Heavy-duty, modular, magnetic-lock ends that won’t fall off — and the 490 Promise behind it.
Frequently Asked Questions
How long does super-chlorination run on a salt pool?
By default the cycle runs for 24 hours at 100% cell output on all three major platforms. Hayward OmniLogic lets you adjust anywhere from 1 to 96 hours, Pentair IntelliCenter goes up to 72–96 hours via the web app, and Jandy iAquaLink counts 24 cumulative run-time hours.
Can I swim while my pool is in Boost mode?
No. During super-chlorination, free chlorine can climb to 5.0–10.0 ppm, which is highly corrosive and can cause skin and eye damage. Wait until your free chlorine drops back into the 1.0–4.0 ppm range before anyone gets in the water.
How much salt does a heavy rainstorm wash away?
Heavy rain can dilute your salinity by roughly 200–500 ppm. To rebuild a 3000 ppm baseline from zero you’d need about 250 lbs of salt per 10,000 gallons, but topping up a rain dilution takes far less — always test before adding.
Why does my pool smell strongly of chlorine after the storm?
A strong chlorine smell actually signals combined chlorine (chloramines) above 0.3 ppm, not too much sanitizer. The fix is more oxidation, not less — super-chlorination burns off those chloramines and clears both the odor and the eye irritation they cause.
Should I use my salt cell to clear a green pool?
No — salt systems are designed to maintain chlorine, not to clear an active algae bloom. Running the cell flat-out against green water puts heavy demand on it and significantly shortens its lifespan. Shock from an alternate source like liquid chlorine instead, dosing 3–5 lbs per 10,000 gallons.
When is the best time of day to start a boost cycle?
Start at dusk or after dark. Unstabilized chlorine degrades in direct sunlight at about 1 ppm per hour, so a daytime boost loses much of its punch to UV. An evening start lets the cell’s output work on contaminants overnight when the sun can’t undo it.
What filter pressure means I should stop and clean before boosting?
Backwash or clean the cartridges once pressure climbs 8–10 PSI above your clean baseline (10–12 PSI on Jandy systems). If the gauge ever reaches 40–50 PSI, shut the system off immediately — clamshell-style filter tanks can rupture at that pressure.
