Buying Guide

Match treatment to the problem

Use enzymes or clarifiers to break down organic debris and improve filter capture, phosphate removers to limit algae food sources, and chlorine or calcium-hypochlorite shocks to eliminate bacteria and rapidly raise free chlorine

Check concentration and dosage

Higher-concentration formulas (e.g., concentrated phosphate removers or enzyme concentrates) treat more gallons per ounce and can be more cost-effective for larger pools

Consider chemical compatibility

Avoid mixing treatments at the same time—add clarifiers or enzymes separately from shock treatments and follow label timing to prevent reduced effectiveness

Evaluate maintenance cadence

Enzyme-based products typically work continuously with weekly or biweekly dosing; phosphate removers and shocks are used as needed for specific events like algae blooms or after heavy use

Prioritize water testing

Test phosphate, chlorine, and pH levels before treatment to choose the right product and dose; phosphate removers are only necessary when phosphate levels are elevated
