Questions & Answers

8 Customer Questions

Is this safe for scaleless fish like Clown loaches?

Answer by Chewy • Mar 09, 2022
Unlike some algaecides on the market, Fritz Algae Clean Out contains no copper and is a selective algae control product that will not harm fish and live plants when used as directed. Fritz Algae Clean Out is effective in both freshwater and saltwater aquariums, fountains and small ponds.

Is this safe for freshwater tank with snails?

Answer by Chewy • Sep 07, 2023
This water treatment is not safe with freshwater invertebrates.

Will it kill existing algae in tank? On plants & decor.

Answer by Chewy • Jun 10, 2022
Fritz Algae Clean Out is formulated specifically to treat existing algae problems, Fritz does not recommend using it as a preventative. Fritz recommends using FritzZyme 360 or FritzZyme 460 to get phosphates and nitrates, which lead to future algae breakouts, under control.

Is it safe for my red eared slider aquatic turtle?

Answer by Chewy • Mar 03, 2025
This aquarium water treatment can be used in any system accessible by pets and wildlife, including birds, amphibians, and reptiles. It is non-toxic and will not cause any harm if treated water is ingested.

An algae bloom is the worst nightmare for large planted aquariums. Fritz algae clean works miracles. But get your shrimp and special snails out first. Highly

Works as advertised

I needed a good algae killer that would not bother my fish. This worked exactly as expected. Nice to have a product that works.
