Quick verdict
The cheap, fast fix for cloudy water that balanced chemistry alone won’t clear. Dose, run the filter, then clean the filter.
Ideal for
- Cloudy/hazy water
- After pollen, storms, or spring opening
- Sand and cartridge filters struggling with fine dust
Not ideal for
- Water that’s green from algae (shock first)
- A substitute for balancing or adequate filtration
The full picture
Cloudy or hazy water often isn't a chemistry failure — it's particles too fine for your filter to catch. In The Swim Super Clarifier is a concentrated polymer that coagulates those particles into clumps large enough for the filter to remove, clearing dull water fast. It's especially useful after a spring opening, heavy pollen, a party, or when a sand or cartridge filter is struggling with fine dust. Dose it (about 1 oz per 5,000 gallons), run the filter continuously, and clean the filter afterward as it loads up with the trapped gunk. It's not a substitute for balanced chemistry or adequate filtration, but as a quick clarity booster it punches well above its low price.

The in-depth review
Cloudy water often isn't a chemistry failure — it's particles too fine for your filter to catch. In The Swim Super Clarifier is the cheap, fast way to clear it.
How it works
It's a concentrated polymer that coagulates tiny particles into clumps large enough for your filter to remove. Dose about 1 oz per 5,000 gallons, run the filter continuously, and dull water usually clears within a day or two. It's especially handy after a spring opening, heavy pollen, a party, or when a sand or cartridge filter is struggling with fine dust.
What it won't do
It won't clear a green pool — that's algae, which needs shock and brushing first. It also doesn't fix underlying problems: imbalanced chemistry or an undersized/dirty filter will keep clouding the water. And over-dosing can actually make things worse by overwhelming the filter, so stick to label rates. Clean or backwash the filter afterward, since it loads up with the trapped gunk.
Who needs it
Anyone dealing with hazy (not green) water who wants a quick clarity boost. At its low price, it's worth keeping on hand for pollen season and post-storm cleanups.

Frequently asked questions
Clarifier or flocculant — what’s the difference?
Clarifier clumps fine particles so the filter removes them over hours of running — easy and gentle. Flocculant drops particles to the floor to be vacuumed to waste — faster but more work. For everyday cloudiness, clarifier is the simpler choice.
Will it clear a green pool?
No — green means algae, which needs shock and brushing first. Clarifier is for cloudy or hazy (not green) water caused by fine particles the filter can’t catch.
How long does it take to work?
Often within a day or two of continuous filtration. Run the pump nonstop after dosing, and clean or backwash the filter once it loads up with the clumped debris.
Why is my water cloudy in the first place?
Common causes are fine dust/pollen, a spring opening, high bather load, imbalanced chemistry, or an undersized/dirty filter. Fix chemistry and filtration too — clarifier speeds the cleanup but isn’t a cure for the root cause.
Can I use too much?
Yes — over-dosing can actually make water cloudier by overwhelming the filter. Stick to about 1 oz per 5,000 gallons and give it time before adding more.
Does it work on cartridge and sand filters?
Yes — it’s especially handy for sand and cartridge filters that pass fine particles. After it works, clean the cartridge or backwash the sand filter to remove the trapped material.
