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 and cheaper than the pool place for exact same product. Shipping was quick.

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!!!!!

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!

This product works well and I'll buy it again but, unfortunately, not online. It was crammed so tightly in my mailbox by the USPS that I thought I was going to have to break the mailbox to remove it and retrieve my mail. If you can find it in a store, it's a decent algaecide that clear up the algae well.

Why did you pick this product vs others?:Best ever

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!

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
