Hi,
I have a 75 gallon tank with 60lbs of LR about 1.5 inches of sand.
I am running a sump and I have a skimmer.
My rock has been in for 4 weeks. and I have 3 fish and a cleaner crew. I am thinking I may need some powerheads, but my LFS is giving me the run around.
I know i need between 10 to 20...
