proper flow for lack of dead spots

[dclegern]

Still working on flow rate/rock placement......etc.

all parameters seem to be cool. just still finding dead spots, random muck attacks, etc...
Overall a beautiful tank, just seems to need cleaning far to often.

75 gallon drilled tank with a 20 gallon sump (skimmer w/cryptic fuge)
Running a mag 7.. with 2 small powerheads to help.
90-100 lbs of live rock in main tank and another 20lbs of rubble in the sump.
normal livestock, cleanup crew, and inverts.
2 150's w/ actinics attached.

any ideas????????

May need to up the flow. On my 75 I had 2 k 4s on it.

I agree with Ruben, the return flow should only be around 900> gph, as you want the flow slower thru the fuge(for the beneficial usage) but you need to increase the flow inside the tank.

I had 4 k4s on my 75

On my 200 I have 3 K4s and 4 of the Evo K14s. It's something like 9,000 gph.

As long as your corals aren't being slammed with water so much so that their skin is being taken off, keep adding! I STILL have dead spots believe it or not.

I have a wavebox with no dead spots...
