I'm plumbing and setting up my 24X24X12 shallow clam tank tonight, and want to go buy a return pump. I'm using a 10 gallon 3 chamber sump, with a 1" drain, and 2 X 3/4" returns. I have two K2's available for additional flow (if needed), but just wondering how many GPH should I be getting for my return pump? Suggestions?

Hotly debated topic.. but the usual advice is 3x turn over for a sump
I would question why you're using a 1" drain and 2x 3/4" returns. Your tank is pretty much 15 gallons, right? 3/4" pipe is rated for approx 600 gph
What are you going to be running in your sump?

Tank is 29.9 gallons. (sorry dimensions edited) 24X24X12 Only real reason for the 1" drain, is that's what it's drilled for. May use a reducer, just not sure yet.

look into something around 1000gph. depending on your height you will only have around 30x turnover which would be great for clams

You'd be a fool to use power heads in such a small tank when it's drilled for more than enough flow from the return. 500-600 gph total flow would be more than adequate for that size tank, easily achievable with a single return pump.

I'm running a eheim 1262 on my cube and I honestly think its not enough flow (for sps) let alone a clam.
Personally I am looking at the sedra 1200 to shoot me into the 1000gph range after headlose

Yeah, i'm thinking that a Quietone 3000 (780 GPH) because the lower the flow through your sump means more filtration happening in my opinion, and then 1 or 2 koralia 2's (600 GPH ea.) I should be just fine.

Eheim are the way to go if noise is any issue for you... I use the eheim compact and its great.

Clams do not require high flow, they do better with low to moderate flow. A 30X turnover in a small cube tank will actually have negative effects on clams, too much flow and too much substrate movement will cause the clams to stress out. A pump rated at around 600GPH will be all you need providing over 10X actual turnover which is better for clams.
