I’m having a hard time setting up my flow either some spots are to rough and some don’t get much flow, I feel like my Duncan, hammers and candy cane are getting to much flow but if I move flow around then it gets tougher for my acans and gsp so I’m not sure how exactly to hit the spot on flow, any help?

Do I just see 1 powerhead at one end and one at the other.. but offset. I’m assuming they’re not controllable. I have the same issue but I think I even have a little more rock than you; and I thought if I had more rock it would help make obstacles (and hopefully not funnel). They look pretty high up but I guess they’re still making a good gyre.

I have not tried this yet but I wonder if you point them at each other if this wouldn’t make too much of a dead spot in the low corners.

I place my corals that don’t want high flow on the opposite end of a powerhead on one side and that still seems too much. I have the ones that can handle more flow kind-of guarding the ones that don’t need or want it. Idk if it would look too dumb to add one rock to deflect flow a little in an area of interest.

I have the same problem but I was able to find a third powerhead and I was going to try to add this on one end above my rock work but turn them all down. Conversely, I’ve been toying with the idea of mounting on the back wall and have two circulating gyres; not sure if this would work with my filtration and if the flow would deflect off the front glass ideally. Not sure where your overflow is.

Hope we can get this figured out for you.

I have a hygger lite 792 gph with controller a Vivosun 1000gph with controller and 2 return pumps with 265 gph each, I’ve found sort of a good spot where all corals get good flow but two the Duncan and hammer, the Duncan been closed for some time though idk if it’s because of my water being milky due to maybe a bad batch of salt or dose cus it all happened after a water change. But my other corals seem fine.

Same. Mine is in the basement so weight wasnt my issue. The wall I wanted it on could have been a longer tank. You gotta pick your battles. The wall it goes on is the exact size for the space. I bought used because I can't afford a new one. Tanks over 180-220g are where the deals are. 220g and smaller they hold their value. I think its because the smaller ones fit in storage better and the big ones are the opposite and a major deal to move.
