Sorry for the noob question, but I am having a hard time finding a clear answer to this. I have a 56 gallon from PetSmart. It is 30 inches long X 24 inches tall. I just ordered the 30 inch Planted+, I just want to make sure what light level I'm going to have with this fixture. I assume it is going to be low. All I am trying to grow is anubias, java fern, and some crypts. So will this light give me what I need at this depth?
