Powerhead Placement

I have 90 gallon with an offset overflow box and I'm having a hard time finding the best location for two koralia evolution 1400's. Any suggestions?
 
i usually place them on the back or side walls and bounce the flow off the front.
 
I think these powerheads might be too strong for my tank. Can too much flow hurt a torch coral or a frogspawn?
 
The torch and the frogs like low slightly breezy flow, def not pounding flow or they wont open. But I def do not think those are too much flow, you just need a good flow pattern. You might need to reposition those corals to obtain a high flow that all.

I have a forgs and a hammer in my tank that is designed for sps corals. I run a MP40, Tunze 6105 and 6095 on a controller so I have a ton of flow and I had to find the pattern to keep everything happy. It might take a couple days

What you could try is one pump on the right side panel 4 inches from the top of the water towards the front glass panel. Pointing accross the length of the tank.

Pump two on the left side panel, pointing just in front of the off center overflow flowing the length of the tank. This will keep detritus suspended and carried into the over flow.
 
I have the same tank, and am having similar issues. Two powerheads (Koralia 1050s) at opposite ends of the tank, pointed towards the glass. The front seems to be fine, for the most part, but not much flow behind the rocks. The overflow box is a bit of an impediment.
 
I have a slightly taller tank with the same footprint, a 110. I put two 1050 on the back corners, high up and pointing down towards the front center. The two return nozzles are directed downward towards the front corner bottoms. Works well. I'll post a pic when I get home if you want.
 
That was my original plan, but my Eheim 1260 is valved back a bit so that it matches the overflow drain, so the water pressure isn't nearly enough to reach the bottom of the tank. I may wind up with two Koralia Nano powerheads aimed towards the bottom of the tank. Not sure about others, but my tank is a FOWLR system.
 
I kinda wish I went with the corner overflow box. I messed around with the powerheads for hours last night but it seems wherever I position them my torch coral is getting whipped around. I might have to change my aquascape.

I would just place them at opposite ends of the tank facing each other. (up top) Corals that like a lot of flow go in the middle of the tank, those who do not go on the outskirts. This type of set-up has worked well for me over the years.
 
I have three, two on one side (one for the back of the rockwork, one for the front of the rockwork) and another on the other side facing slightly upwards to create surface movement and slightly blow around my corals. So if you think about it, everything is circulating.
 
Powerhead placement probably took the longest and most tweaking for me. Honestly took me over a week of trial and error to find the balance. I have two Koralias in my 75g, one Evo 1400 and one Koralia 4 place on opposite ends and just took some tweaking to get it right. They are largely facing each other but angled slightly up and towards the front.

Yes Please...same tank similar problems...

Ok. Here's a pic of the 110 predator tank. There are two 1050 Evo's, plus an effective 700gph return pump via two nozzles.

Here's the reef tank, 150 gallons with twin corner overflows, but similar principle in powerhead placement, with the tank kind of divided into two 75 gallon areas. The powerheads are all 1400 gph Evos, though

Is it bouncing off the glass? If i try and do that i end up blowing sand everywhere.

Yes, it is bouncing off the glass. I purposely got medium grain substrate because I wanted to use flow to keep debris and detritus off the substrate. If you have finer sand and it blows around too much, you can always direct the flow higher on the glass.
 
This is my setup. I played around with them for a while and it seems a little better.
