I finally found what was up with my corals!

[TheCoralReef731]

For the past year my SPS corals have been dying and not doing very well. The cause of this was unknown until recently, when I had the return pump's gph lowered for about a week. The polyps on the SPS have came out fully and colors are finally starting to show.

I had about 300-350gph coming out of my Mag 7 in my 25 gallon tank. Was that way too much? (my rbtas liked it a lot)

Yah Know i'm in the same situation as you, I have a 40gallon breeder and I'm always wondering if I have to much or to little flow...

I'm knida new to the hobby and I just picked up a baby clown from Rod, and he looks like hes getting a work out in my tank....

I dont have anything extreme just 2 Rio 600's powerheads....

I dont wana steal your thread, just wanted to jump in

I supposed we both could experiement and reduce the flow for a while see what results we get

Maybe the the water needs to be diffused more. Corals don't like a jet of water coming at them constantly. It maybe as simple as putting a hydor rotating deflector on your powerheads.

yes a mag 700 on a 25gal is like an overkill you might want to lower it...

Happy Thanksgiving

i don't think a mag7 is ENOUGH flow for SPS. i have a Mag5 and two MJ1200s plus a minijet400 that keeps the back of the tank detritus free.

Ugh, to much flow, to little flow...

hows a newbie like myself supposed to know how much flow to have?

Explain diffusing more. Do you mean to spread the flow of the water that comes out of the pump?

 

[adamatic]

I agree that the flow discussion is confusing - I still don't entirely understand the purpose. Is it to move waste away from sessile corals, distribute nutrients and food to/from corals, or does it contribute to growth by creating physical force because of water movement?

I realize it's most likely a combination of all-of-the-above but what function is most important??
