Review on 🐠 LEDGLE Submersible Aquarium Lights: 13W, 11W, 9W, 7W | Water Clean Green Clear, Waterproof Clean Lamp for Aquarium by Leslie Morrison

I bought this to solve an algae problem in my aquarium, in fact I've only used it twice and it has drastically reduced the amount of algae in my aquarium. The only thing I didn't like was that it's written in a different language and therefore doesn't explain how to use it. All in all a great product. Just don't put it with fish or it will kill them. You have to put it in a filter
