Pool Complete Weekly, 3 Liter, Single Pack | 3-in-1 High-Intensity Clarifier & Cleaner, Prevents Waterline Buildup, Removes Phosphates, Keeps Water Clear

I have used this for the last few years. A once a week treatment removes the phosphates that cause the chlorine to become ineffective, causing algae growth- even when the water is over 90°in Phoenix. The water stays crystal clear.

Great product. Easy to use. No algae problems for my pool.

I've become a fan of bioguard products, and only use this brand now. Yes a little more expensive, but the products just work. I dump three cap full of this into my pool each week and it remains clear and phosphate free. In the past my phosphate was over 3000, I used their phosphate killer and it was gone I one treatment.

I have been spending money trying different products for years trying to get my water pristine! And not until now have I ever been able achieve sparkling clear water! No algae and crystal clear!! Amazing product with guaranteed results.

It SEEMS to keep the water clear.

Product really works great. Once a week I add pool complete to my pool Keeps my pool water crystal clear.

It works as described

This stuff is great!!
