How much water flow

Ranchhand02 · 12/28/2008, 09:28 PM

I am thinking of upgrading my powerheads to a larger size. I am thinking of getting two Hydor Koralia #3 (850 GPH each). I curently have a 75 gallon single corner flow tank. I have a couple of anemones, a few mushrooms and a few zoos. I am wanting to get a few more zoos and a few other corals. Will this be enough flow? How much flow do you recomend?

for those that is more than enough, a whole different story for SPS though (what i'm dealing with)

Do you think that it would be to much flow?

I have a 75G with an external overflow, 2 K4's on a simple wavemaker (timer), works *great*. The K4's sometimes chatter a little on startup, but they were not really advertised to be used with a wavemaker, so I just deal with it. At first I thought the K4's might have been too much for the tank size, but after a couple weeks of fiddling, I got the flow right and wouldn't trade the K4 setup for anything.

Happy Reefing.

Where are the powerheads placed in the aquarium?

MarineFlake · 12/28/2008, 09:59 PM

One in the rear corner left and one rear corner right.

Are they pointing at each other? Can you post a pic?

wont the constant on/off kill those koralias? thats wht i have read more than once...only reason i havent put my two K3's on one

MarineFlake · 12/28/2008, 10:14 PM

No recent photos, but essentially they both point toward the center of the tank. Between them lies my overflow box, helping to dispurse the flow.

Ranchhand02 · 12/28/2008, 10:14 PM

Have you had good luck with your K3's? Are they quiet?

MarineFlake · 12/28/2008, 10:20 PM

K3's run 24/7 and have never been a problem for me.

FranktheTankTx · 12/28/2008, 10:23 PM

I run 2-K3's on my 54g corner. They are on opposite corners (about 36" apart). I would consider K4's for your 75g since they would be 48" apart. Flow is good!

What about Tunze nanostreams?
Those have some killer flow rates.
I'm thinking of replacing the two K2's in my 46g with two of the Tunze 6045 (1189gph each).
