If you want to have truly crystal clear water, a UV Sterilizer is for you. Or, perhaps you have a problem with parasites? Whatever the case, a UV sterilizer will clean your water without the use of harsh chemicals. The way that a UV sterilizer works is that it shines a powerful beam of light at a trapped column of water – this will kill organic matter like algae and parasites, while leaving your fish unharmed.

You really can’t go wrong with a UV sterilizer from Fish Fans.
