My 43 hex returns water from the sump at about 250gph. I have one cheap power head 125gph. This was fine for fish only. Should I buy a bigger return pump or just powerheads? If I feed brine there is always some left on the sand bed that the crab gets. I thought excess food on sand bed meant my flow was to low.

It means you are feeding too much :)
Actually for a hex you may need a few more PHs pointing in random directions to get better water flow. What animals do you have in there now?

animals

Just 3 damsels, 2 hermits, 2 snails and one sally light foot.
I'll be adding corals when the tanks ready. I just want all the equiptment in place when the time comes.

snails

I'm sure I could use more. My huge algae bloom is just now starting to die down. I cut back MH light to 8hrs. The local store I use is Aquarium Paradise and they are just getting relocated. No snails at the present. I am now in the process of getting the "aquascape going up" . Being a hex and deep its kind of a pain to get the right ratio of rock and water. Do you know if adding rock to the sump would create the same biological effect.

Thanks
Don

Hey DonW,

I would say if definately does. Many people put both a DSB and LR in their sump to achieve additional biological filtration.
