To safely get rid of algae in your red-eared slider's tank, you can reduce the tank's lighting duration, clean the tank and filter regularly, and avoid overfeeding your turtle. Introducing algae-eating tank mates like snails or shrimp can also help naturally control algae growth. Avoid using chemicals or algaecides that can harm your turtle.

Algae is a result of high levels of phosphates in the tank. A Phos-Ban Reactor is used in mainly saltwater tanks, but can be used in freshwater tanks also.
Too much sunlight on the tank!!
