8’ 240 gallon flow techniques

[Ribo15]

Hey guys. I’m looking for some input from people with long “narrow” tanks. My 8’ tank is 2’ wide and high. I’m wondering how do you get good random flow across the tank? I feel my corals near each end only get blasted with flow from one side and I’m wondering what some of you do to overcome this? Thanks for any help.

It sounds like a good application for gyre pumps near the surface. That should give you strong flow at the surface and some residual laminar flow lower in the tank. The tank you're describing isn't very deep, so one on each end would provide plenty of water movement.

I have a 7 foot long 260g tank. I have 2 wave makers on each side, 2 returns each split into two, and two gyres mounted long ways on either side of my overflow box to get any detritus from behind the aquascape. It's probably overkill, but my tangs enjoy all the flow.

Okay, I currently have a gyre on each end but mine are horizontal not vertical and I have dual returns each split also plus 1 power head. From the sounds of it I’m on the right track. It just worries me that some corals see a lot more flow from one direction than the other but sounds like it’s okay. Thanks for the input guys!

I have a 79x25x25 with 2 RS 45 gyres each end and 2 mp40's on either side of center overflow. mp40's are centered back. I only run 40-70 %. Plus 2 returns

You have 4 gyres in there??

Barrel roll the water.
What are you currently using thats not working? What's your budget?

Currently 2-4K gyres. One on each end with opposing schedules. One jebao SOW-20 to blast behind the rock structures for detritus. Then the dual returns on each end. Budget is what ever is with in reason. MP60s I’m leery of with the 1000$ price tag and some reliability issues I’ve read

Panta rhei and abyzz make flowers pumps if a little more $ isn't out of the question.
