3 mp40s too much flow for 180g mixed reef?

[rskillz]

I have a reeflo dart return pump (3000gph) with 3 mp40s on my 180gallon. Starting to wonder if its overkill. I have to dial them WAY down to prevent a sandstorm, and I don't even have fine sand.

I know for a SPS dominant tank 3 or more would be fine, but beginning to think eliminating the one on the back wall would make sense.

Any opinions?

I had two 40's in my 90 gallon and loved it. I, for one, don't feel as if it's too much but that's just me. What kind of sand is it?

Reeflor special grade.

No first hand experience with that. I had Fiji pink in my tank.

I have the same tank as you and the same sand too Ryan. I have 2 MP40 and 2 K4. I rarely have my MP40's ramped up, when I do it blows my fish right out of the water column and they hide all the time. It also creates dunes in my sandbed.....so to me, a lil overkill.

Hmm. I've got four on my tank and no real issues... Of course the two along the back wall are dialed waaaaay down.

I think alot of it has to do with aquascaping, I have minimal rock

 

[crewdawg1981]

Same... Ive got a very open aquascape.

I have 2 mp40s in my 175. Sometimes I wish I had either a third MP40 or maybe an MP10 to fill in a little. I think your good with 3. Just dial them in.

run all three... decrease their maximum flow until you've got flow where you want it..


you can run an MP40 in a 30gal cube if you want..

I always want more vortechs to get all the dead zones.
