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

Great product! If you are tired of spending a lot of money trying to figure out how to get rid of algae in your swimming pool, this is it! It is super concentrated so you only need a small amount. My pool gets heavy use with kids and grandkids and sometimes 4 dogs. Plus a lot of wind which brings in micro debris. For two seasons I've had yellow algae in corners which I had to brush daily and did not get any results from other pricey products. After the initial use and then followed a week later with 2 oz, I have not seen any algae anywhere! This one quart bottle using 2 oz a week for a 10,000 gallon pool will last the pool season. So definitely worth the price!

The pool had a green algae bloom. Green for days even after shocking. One good dose, as directed on label, and the green was gone in less than 24 hours. 16k gallon pool and used about 20 oz. Apply in the evening or when sun is not on the pool. Great!

As described

Worked perfectly as described. Works great for the control of water bug infestation as well.

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.

Great product

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!

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!!!!!
