Im getting a 28g HQI from another site that has been souped up a bit in the lighting dept. and my question is how thick should my LS be with 30 lbs of Lr?
It really all depends on how deep of a sandbed you want to have. I personally like a deeper sand bed, especially if you are going to have any burrowes like a shrimpgoby. I would go with 30 pounds of LS. I have 12 pounds in an 8 gallon tank
