Can I get some help please??? no one answered my last post I have a 29 gallon 33lbs live rock and now have two powerhead one 150gph and one 110 gph one is pointed at the surface and the other at the front glass. I switched the 110 to the 500gph circulation mode and my clown was getting pushed around but he was swimming into the current. he looked like he was getting worn out. I have now switched it back to the 110gph powerhead mode and my clown wont swim now just stays in the top corner i dont get it someone please help!!! where should I put the powerheads!?Thanks everyone for reading

In my 30 gallon cube I just had my powerhead in mid level slightly pointed down so the corals had flow. It was 400gph though and I had an overflow/surface skimmer so I never needed to point the powerhead at the surface for oxygen exchange. Maybe if you're going to use 2 powerheads get 2 that do 200gph otherwise my set up was great with one 400gph. My roomy has a 30 gallon as well and he uses a 400gph maxijet and his fish love it. Your clown is probably stressed from too much current. You should give it a couple of days and let him settle down. My clowns stay in the corner like that if I change anything. They're emotionally sensitive lol. Hope this helps.

How long have you had the clown? It could take it a little time to get used to the changed environment. i wouldn't worry too much. Clownfish are pretty resilient.
