BioGuard Algae All 60-1 Quart, Non-Foaming Algae Preventative, Non-Staining & Non-Foaming, Ideal for Swimming Pools with Attached Spas or Fountains

Truly non-foaming and works great. I switched to something else for cost savings and regretted it immediately. This is the superior algae product.

Great product

I have used BioGuard products for over 20 years. I have never been disappointed. They solve the problem with my swimming pool.

I think this is a good product and may have worked even better had I been able to make everything about the water perfect. But as it was -I could not and 4 bottles later it wasn’t much better than when I started.

This is literally the best and only product we use all summer and on closing our pool. Have zero problems with algae all summer long, take the cover off when opening pool in late spring and seriously pool water is crystal clear. We have tried other products but will battle algae. This product is amazing!!!!!

We have been struggling with white mold all this season, then started getting some green and brown colored algae. Only certain things kill white mold and We have been scrubbing the walls, shocking, vacuuming to waste, and back washing, making sure we had tabs in, and nothing was working. So I decided to get this. I checked for metals in the pool water before using and thankfully we didnt have any, so we used the amount for slight growth on the bottle, and bam! Next day every bit was gone, even what was behind the steps. We have a 15x30 above ground pool, with a large capacity sand filter. This worked great! Only drawback was having to buy the strips to check for metals to avoid staining the pool liner steps etc. Highly recommend!

Bioguard is the only brand I'd ever use.
