BioGuard Algae All 60 | Non-Foaming Pool Algaecide

BioGuard Algae All 60 is a 60% polymeric quat algaecide — the highest concentration of polyquat in the BioGuard line — and it's the product BioGuard specifically recommends for pools with attached spas or jetted returns.

That recommendation comes down to one property. Ordinary quaternary ammonium algaecides are notorious for foaming, and a pool with a spillover, a waterfall, or jetted returns turns a quat dose into a persistent head of foam that can last for days. Algae All 60 uses a polymeric quat rather than a simple one, and polymeric quats deliver the same algae control without the foaming. If your installation has any real aeration, this is the difference between an algaecide you can use and one you can't.

It's also non-staining and contains no metals — no copper, no silver. That matters more than most people realize: metal-based algaecides are genuinely effective, but they carry a real risk of staining plaster and other surfaces when pH drifts low or when metals are already present in the fill water. A metal-free algaecide removes that risk entirely, which makes it the safer choice on light-colored plaster and for anyone on well water.

The formula is effective on all types of algae and, unusually, works across all pH ranges. Most pool chemistry loses effectiveness as pH drifts — chlorine in particular becomes dramatically weaker above 7.8. Algae All 60 doesn't have that problem, so it keeps working through the pH swings that happen in real-world pool operation. It also won't affect pH itself, so dosing doesn't trigger a rebalancing job.

Dosing is scaled to the situation, from a light maintenance dose every five to seven days up to a heavier initial treatment when algae is already present. Swimmers can return 15 minutes after application.
