Help me with flow for my 25g

[CleverBs]

I have a single 750 koralia in my tank now but feel that I need flow from the other side of the the tank to keep things moving. Should I put in a 425 or 250 koralia?

I'd go with a (550) For the other side - flow is good. With proper placement you'll be in great shape.

I feel that that's to much current for my size tank. I don't want my corals getting to much current and getting overwhelmed by it.

Well, obviously you will know best as it is your tank. I just know Carey uses (2) 750's in her 29. I was using (3) 750's in my 54 and upgraded to (2) MP10's. In total I have about 3500 gph in my tank and the fish and corals seem to love it!

Out of your (2) initial options I would at least go with the 425.

Yep, if you have proper placement the flow should be fine. The 425 would be the minimum I'd put in, I have 2 425's in my 20g and they don't even reach the opposite side as far as flow.

Hmm ok I'll go with the 425. Can anyone tell me where I should place them in my tank?

I'd go with the left side, the one that doesnt have a pump right now.
