I have a 40gal AIO cube. Stock pump didn’t seem to provide enough flow for corals so I added a cheap powerhead (1050gph) I found online. It isn’t programmable. Do I leave it on all the time? I’ve been unplugging it for feeding but wonder if I should turn it off at night or put it on a schedule so the fish don’t have to swim so hard. Am I an idiot for wanting to give the fish a minute to relax? Clown, Royal gramma, bicolor blenny and a YWG. Gramma and blenny usually sleep in the rock. Goby was added today but will hopefully have a cave and tunnel once I add a pistol shrimp.

You can leave it on 24/7, I do. I turn it off for feeding and sometimes to give everything a break but it’s not necessary. Some people will ramp their power heads down at night, I don’t.

Variable speeds rather than blasting one direction and speed full time is best
I’m thinking I need to replace it with something more programable eventually. It is on its lowest setting and still seems to create quite the current. If I am not careful with placement/direction of flow it will cause turbulence in one corner and kick up sand. These things aren’t that expensive so I will research options. If you have any suggestions I am all ears- It’s not a large tank- 40 cube AIO so display is closer to 35.

I would definitely find something a little less on GPH and programmable. I thought the same early on about giving the fish rest lol I have 2 power heads and filter moving water in my 20 g and everyone is happy

you can see placement here- right side. Height is around 1/3 down. It pushes quite a bit of water so aiming at the surface nearly turns this thing into a fountain.
