Return pump turnover question

[Gluestick]

My LFS dealer sold me a 500gph Mag Drive pump for my return on my 90 gal Megaflow tank. Is this enough flow???

That's not enough total flow, but it's probably fine for your return pump. I wouldn't try to use the return pump as the sole source of flow in most any system. A closed loop or powerheads are two ways of adding more flow.

I agree, 500 gph is plenty enough going through the overflow, but you will want to add some powerheads for additional flow.

Fine for a return pump

And I was thinking 3 maxijet 1200s, for flow. Sound good?

 

[bertoni]

Sounds fine to me.

MJ 900 versus 1200

MJ 900 versus 1200

FWIW, i'd go with 4 MJ 900s instead of 3 1200s. two reasons: 1). MJ 900 puts out 230 gph, the 1200 puts out 295 gph--not a huge difference IMO. 2) MJ900 draws only 8.5 watts power; the 1200 draws 20 watts.

thus, you could do 4 MJ900s with one in each corner (drawing a total of 34 watts and pushing over 900 gph) which would have more flow (simply put more GPH) and less power consumption than even 2 MJ 1200s.

but that's just my opinion and as we all know, opinoins are like [profanity], everyone has one!
