Lo-Chlor Pool Algaecide for Swimming Pools -Single Treatment Lasts 3 Months, Effective Algaecide for Pool with Unique Organo-Copper Complex - Black, Mustard, and Green Algae Killer for Pools (32 Oz)

Works beautifully and we have a very large pool. Only used about a third of the bottle with excellent results.

Used this for years and never had an algae problem. Was recommended to us by our friend that does pools. Highly recommend. Worth the price.

This algaecide has proven to be very effective against algae. We live in Orlando where we gotta be on top of the pool due to the harsh weather during the summer. One thing I like about this product is the fact that you only need to apply it every 3 months, making pool maintenance much easier and one less thing to be worried about every week.

This Lo-Chlor Algaecide really wasn't any better than just using a few copper pennies in the skimmer basket, it was too weak to realize any help. Will not buy this product again, and not blaming seller, the contents is just too weak.

We've purchased this product many times. It works great, we have never had algae in our pool. We use it regularly.

This product was recommended to me by my local pool supply store to help control black Algae. It appears to help.

Using this has kept my pool sparkling and free of algae. I have not had to brush it or use any chemicals other then chlorine. It is FANTASTIC!

Pool remains crystal clear and algae free with this additive.
