Hydor Koralia Evolution Powerhead(s)

[chazz512]

I have a 85 gallon that has been set up for about 12 years. I have about 40 lbs of live rock with plenty of red and green mushrooms growing on it. I want to add some corals but need to add some water movement in the tank before I do so. I am going with the Hydor Koralia Evolution Powerheads but I am not sure if I should use 2 - 550's or 750's to get movement on both sides of the tank or 1 - 1400 on one side of the tank. Any Suggestion or recommendations?

on my 75gal im gonna try two 750s and one 1050 or 1400 HTHs

I would personally go with two evo 750s. One on either side of the tank...

Where are you placing them in your tank?

ok so the idea is that the more powerful powerhead will push the water all the way down and round ur rockwork well the rest of ur powerheads make random flow or fill in some spots with no flow. This is no design/schematic lol....
just a drawing and an idea. My tank is a penninsula tank so it can be viewed from both sides,,,
Im also not sure if i will be able to place a powerhead on my overflow but i think i should be able to. You should be able to click the pic to enlarge it!

Great diagram. I don't have an overflow in my tank. Do you think two 1400 would be too much on either side of my tank?

really its personal preference and some things do factor in....
try two 750s on both sides and watever filtration output u have, try and mix it in as well...
if need be u can get the third....either another 750 or a 1050 or even a 1400 later...
