I use a AC 50 (I think or 70) & MaxiJet 1200 & 400gph in my loach tanks,2 55g & 75g.
A BIG warning I had a small histrionica loach that lived INSIDE a powerhead, he swam into the outlet side. Even though I knew he did that & decided to remove it, he stayed in there when I took it out. I couldn't see him & thought he must have come out but NO, he fell into the sink & down the garbage disposal. I was able to rescue him but he & eventually the rest of the histies died from a bacterial infection.
Now with my replacement histies I put plastic mesh over the outlets to prevent it happening again. I used the plastic mesh from an onion bag, not great looking but safe. I use the strainers or a Quick Filter on the intakes.
