What to do

[dwair]

I have a 90g 4ft tank with 1 MP40wES now.

I'm thinking of either selling/trading it for 2 MP10wEs instead. What do you think? Not enough flow?

Seems like the MP40 is to much with just the 1, but it doesn't do well over on the other side, so I need another PH on the other side. So I was thinking 2 MP10s instead.

I know a couple people using (2) MP40s in 4ft long tanks. Works well, just run them at less power. I've never dealt with an MP10, but I would think they would have to be maxed out to get a 90g moving.

Yes, I ran both on my 110 I had. The 2 mp10s weren't enough for what I wanted to do. I then upgraded to 40s and ran them at about 70% our so.. Much better..

I've got two MP40's on my 75g 4ft tank. I run them through my apex with one on constant at 10% and the other on different modes up to a max of 35% and everything in the tank from SPS to softies seem to like this combo.
