Okay, I've gotten so many people telling me this lighting system I have for my 29 gallon tank is low, medium, and somewhat high. Can someone please give me a straight forward anwser! I have a T-5 48W over it, which is about 1.6 wpg. But I know the watts per gallon rule doesn't really apply to T-5 lights. So which is it, low, medium, or high. If it's high I'm going to buy stuff to test the Kh and Ph and put DIY Co2 and dose with liquid ferts. I don't want to have to buy the Kh and Gh testing and the DIY CO2 if I have low light, and all that would cause is a algea bloom.
