How do I stop my fish tank water going green? The most effective and effortless way to get rid of Green Water is to install an Ultra-violet Sterilizer on your aquarium. As water passes through the UV chamber, suspended algae are eliminated, along with many disease-causing organisms. The result is crystal clear water in a matter of days.
Why is my fish tank turning green so fast? Fish tanks turn green with algae, which need light, water and nutrients to grow. Algae spores are airborne, so even if you start off with brand new everything, coldwater, tropical or marine, your tank will go green.
Do LED aquarium lights cause algae? Contrary to what you may have been told, LED lights do not cause algae growth any more than other aquarium lighting options. Some LED lights also have adjustable light options to dim or brighten the light according to your fish’s needs.
Does green water harm fish? Green aquarium water is not considered dangerous to fish. In fact, many fish happily live in green-colored water in their natural environment. The same goes for plants. While the algae that makes up green aquarium water feeds on many of the same nutrients that your plants do, it shouldn’t cause any direct harm.
