AlgaeFree Pool Blocks are suitable for: Above‑ground pools In‑ground pools Saltwater (chlorine generator) systems They can be used with most pool filtration systems. Always ensure proper water balance and circulation when using algaecides.
No – AlgaeFree Pool Blocks help control and prevent algae, but they do not sanitize water on their own. You still need a proper chlorine or bromine sanitizer at recommended levels to kill bacteria and keep water safe: Free chlorine: 1.0 – 3.0 ppm (pools) Free bromine: 3.0 – 5.0 ppm (spas) Algaecide works with your sanitizer plan — not instead of it.
For proper application: Ensure your pool pump and filter are running. Place one AlgaeFree Pool Block in a skimmer basket or floating dispenser to allow slow release of algaecide into circulating water. Use one puck per ~25,000 L (~6,600 gal) of pool water each month for ongoing control. For ongoing maintenance in larger or hotter conditions, you can adjust to approximately one puck per ~50,000 L (~13,200 gal) once algae is under control. Always maintain chlorine levels and balance water chemistry alongside algaecide use for best results.
AlgaeFree Pool Blocks provide: Ongoing algae control and prevention — up to 2 weeks per puck Reduced chlorine demand because less algae means chlorine can focus on sanitizing rather than fighting growth Long‑lasting protection throughout the season Easy, low‑effort maintenance — ideal for busy pool owners who want added protection between shock treatments or sanitizer dosing These are especially helpful if your pool is in full sun, prone to algae growth, or exposed to environmental debris that can feed algae.

These solid tablets work over time to protect water from green, mustard, and blackspot algae while reducing chlorine consumption needed to maintain clean water.
