Buying Guide

Match product to your maintenance task

Choose enzyme-based clarifiers for routine organic-waste breakdown and phosphate removers when algae-prone or high-phosphate water is present; use calcium-hypochlorite shock for periodic heavy bacteria or chlorine-level resets

Check compatibility with sanitizer type

Confirm the clarifier or enzyme is compatible with your pool's sanitizer (chlorine, bromine, salt systems) to avoid reduced effectiveness or chemical interactions

Dose by pool volume and frequency

Follow dosing instructions based on pool size and plan weekly treatments for enzymes/clarifiers while reserving shock treatments for scheduled heavier maintenance or after contamination events

Look for phosphate removal when needed

Phosphate removers help limit algae food; include a phosphate-targeting product in your weekly routine if tests show elevated phosphate levels

Balance cost and coverage

Compare price-per-treatment and pack sizes—multi-pack shock treatments and concentrated enzyme formulas often offer better value for recurring weekly use
