Broad-spectrum algaecide that kills and prevents green, black, and mustard algae.
R338,10
Wipes out all three algae types.
A broad-spectrum formula that kills and prevents green, black, and mustard algae — the three most common pool problems. One product covers every variety.
Prevents the problem before it starts.
Used as part of a regular maintenance routine, MSA II keeps algae from ever taking hold — so your pool stays clear between cleans without extra effort.
A name you can trust on the chemistry.
BioGuard is one of the most respected pool chemical brands on the market. MSA II is engineered for reliable results, not guesswork.
Fast-acting liquid formula.
Liquid format means it disperses through your water quickly — no waiting for tablets to dissolve, no slow release. Dosing is simple and precise.
There's a version of pool ownership where you stop reacting to green water and start preventing it. Where your pool looks the same on a Monday as it did on Saturday. Where chemicals work in the background so you don't have to.
Most algaecides target one or two algae types. MSA II handles all three — the green bloom that appears overnight, the stubborn black spots on plaster, and the cloudy mustard variety that resists normal chlorine. One product. No gaps.
When your pool looks exactly right — clear water, clean walls, nothing growing where it shouldn't — this is the chemical doing its job quietly in the background.
