1/2" to 0.5mm valve?

If you are having issues with it pumping too much water - nevermind my post

If you are having issues with it because it splashes ...

Put a larger hose into the water that the output feeds through

The black hose is my ATO feed, and the clear 1/2" hose is under water a bit

I see what you did there Greg. Clever

Actually the problem is, the 0.5" pipe is pushing out too much water (bigger surface area) and hence my corals didn't like it (maxi mini was like WTH); I want to limit that.

I think your idea will help too. Correct me if I am wrong, but with your method, you are pulling in less water right?
