GPH Question

[CheckSix187]

Hello everyone! I was recently lucky enough to find a 90g setup that was in my budget, and i just have on question, how much flow do I need to have a successful and healthy reef system? I currently have a Koralia 2 Powerhead that puts out 600GPH left over from my old 30g, also is it better to have one large powerhead or a few smaller ones so you can control the movement a little bit?

Thanks guys :spin:

Many smaller powerheads, that way there are no dead spots.

From what I read, and follow is that you have 2 different flows in a tank.
1- is for your filtration, this should be 5-8x turn over.
2- is actual water flow in a tank, softies and lps like 5-8x turn over within a tank, and sps like 10x turnover. I am not an expert but I have no problems in my tank so far.

Not to many small power heads you dont wanna mess with the temp in ur tank. specially on a hot day...get rid of everything u have and get your self a mp40 that should do the trick.....

your also gonna have your return pump flowing on the opposite side of the mp.

Richie - If I had a dollar for every time youve helped me, well id have alot of dollars, so 10X turnover for a 90g tank would only be 900 GPH flow? Thats not bad at all

Ricardo - Just wanted to let you know the tank is lookin great! thanks for all the help and the great deal, it was nice to meet you

No problem at all just keep saving all those $$. when you get a chance put a pick up of your tank then we could see exactly where to put the Koralias.
And when you are ready for your corals i'll give you some.
