Please Note that this light only clear the algae and green in the water,but can not clean the black algae attach on rock and tank.
IT is a Wrong way that many people use it as the original light in a tank with fish. The best way is using the light in a sump ,
if you do not have a sump that fits it,may be you can divide the fish tank two part with a Opaque plastic board,use the light in the part which the fish can not reach.but please make sure the water can flow over the plastic board,so that the light can clean the green in the water.
Because as bait fish and other organic matter will produce, heterotrophic algae will multiply it immediately decomposes the organic matter, the large population of heterotrophic algae caused a decline in water clarity.
For this case,you need this light to clean the algae and make the water clean. I suggest that you should use the light 3-4 hours once in 2-4 days.
But because The number of algae is mainly determined by the amount of fish feces and the water temperature,you should find the best clean time by your watched.
