water flow and the Oceanic biocube 29......

[Monkey55]

I have a oceanic biocube 29. I am concerned about flow, because it seems that there is a lot of poop on my sand bed. I have:

12 - hermit crabs (blue)
3 - large mexican astrea snails
2 - stallera astrea snails
3 - trochus snails
6 - nassarius snails

and this crew does not seem to keep up. I am getting 8 more nassarius snails and a fighting conch next week. I have a sapphire protein skimmer. So I know that enough oxygen is getting into the water.

What I am concerned with is that the pump that comes stock has a flow of 250 gph. Now I have looked around on the internet and some say it is too much and some say it is too little. Since I know that reef central people are the wisest aquarists in the world, I started this thread. I have been thinking of putting a larger return pump in, and splitting my outtake with a locline Y fitting. to disperse flow. I am thinking that a pump with 350 GPH would be good? (what do you think, my tank only realistically hold 23 Gallons of water plus sand and rock)

My questions are:

1. Considering I have a heavy bioload in my tank, and a lot of corals, how much flow do I really need? Should I just get more snails?

2. If I need more flow, what pump will fit in my third chamber?, that is common to find (i could get it from a local LFS)

3. If I should install a Y fitting and locline, what directions should I point the two outtakes in?

Thank you, I really appreciate the help everyone has been, you have made this hobby more enjoyable and stress free for me>

Cheers
