Powerhead question

I was wondering if you need an air pump with a power head? I am getting the Maxi jet. Also, should I get 2 160 gph or 2 106 gph for my 50g reef tank? Thanks! http://www.drsfostersmith.com/Produc...&N=2004+113040

I would go with at least a MJ-900 and one of the MJ-1200. IME, the 4&600 models are not large enough for your tank volume. I do not use the venturi feature on the powerheads, but they do not need an air pump to work. They suck in air (if you have the tubing accessories attached) by the force of the water movement through the narrow outlet.

So your saying to get an MJ-900 and an MJ-1200? Wont 2 MJ-900's be enough?

I would actually get two 1200s. No need for the air hose.

Yep, at the very least. I actually agree with lando and would get the 2x1200's.

Ok thanks for the help! Should I aim the down, up or in the middle?

I have a 55G tank, two MJ-1200s and don't use the air hoses that come with them.

I would place them both in the back corners pointed toward the middle front with at least one directed towards the surface (not straight up!) to create surface disturbance (and the resulting oxygen transfer). The other one can be directed similarly or more towards the middle. The two currents should somewhat meet in the front and "bounce" off each other with sort of random currents through the rest of the tank. You may need a 3rd small powerhead to have more random colliding eliminate any dead spots.

Ok cool. So I should point them in the middle and one towards the surface. Not towards the corals right?

No, in general you don't want your corals receiving the blunt force of the ph flow...I believe that's called laminar flow? Most corals like random, chaotic flow...some strong, some not so strong.
