Verified Purchase
Struggled with my pool for years. Once I determined it was mustard or yellow algae this product made all the difference. Only issue was determining and measuring the correct amount as my pool is smaller and I needed less than the container. However, I figured it out and this solved my problems. Now my pool is looking fantastic, my water stays balanced and I use far less chemicals in my pool maintenance now. Great product

Algae Cleaner
This product works well in an algae pool but make sure you look at the amount prior to buying it. Measure your pool up against the amount you will need. Size makes a difference.
