In The Swim Algaecide 60 Plus for Swimming Pools - 1 Quart

We had a bad rainstorm and the next thing you know I had black mustard algae growing in my pool. I have tried in the past with other types of algaecides and nothing works except for this type. Happy with the price and delivery time. I dumped the bottle in the pool and a few days later all the algae was gone! Water stays nice and clear as well.

Algaecide 60 plus worked great for me. You just have to make sure you also use a brush to get rid of the algae completely. It doesn’t do the job on its own.

Worked great. Fantastic algaecide. I like nonmetallic algaecide as it does add copper to the pool which stains (do buy into the crap that the metallic stuff doesn’t just because they say so). This stuff is the best I’ve used.

This additive works great. But the container is terrible. You can wipe the container down after using it but the next time you use it the bottle will be slimy. Fix the the container and you get 5 stars

This is the second season using this Algaecide to maintain my pool during the summer and winter seasons. It is extremely effective in keeping the pool algae free. It does not foam or leave a residue. I simply pore a couple of ounces in the skimmer once a week. The bottle contains enough liquid for the entire season and my pool looks phenomenal.

Have had good results using this algaecide in our pool maintenance routine. It’s easy to add and helps keep the water looking clear without excessive foaming. A little goes a long way, and it seems to work well alongside regular chlorine treatments. Great to have on hand during warmer weather when algae can become a problem quickly. Reliable product and good value for pool owners.

It seems to do the job. I haven’t seen any phone and the water is clear.

Use for weekly pool maintenance to prevent algae. I have used for years and never had a problem with algae. Does not make the water cloudy and no strong odor.
