??size seio pump for 75 gal reef

[mpls man]

I'm looking at the seio pumps for little more flow /
right now i have a Ocean Motion squirt wave maker and was wondering if i should add any more flow on the sides to the bottom, i have 2 clams and know they dont like a lot of flow across the mantles, ..
so should i invest in 1 or 2 pumps or will it be too much flow?
i would like the detritus from collecting in the sand...
any help or advise would be great.
thanks

I would go with the 1500 honestly, mainly because they are coming out with a controller that is going to be able to run the 1500 and up.
I have two 820's that I am using on a 24" long tank and I don't think they are too much for that.

ok my next ? would be is that going to be too much flow around the middle of the tank for having clams and trying to keep ditritus from building up at the same time?
thanks.
