powerhead - flow

[sbgreen]

A quick question.

I have a 50 gal, 50 pounds live rock. I had 2 low flow powerheads that did the trick, but i broke one yesterday and want to order a new one, inexpensive is the key.

I am looking at the maxi jet from Marine depot

MP400 120V/60Hz 5W 106gph (400lph) 29" 3.5" L x 2" W x 3.00" H
MP600 120V/60Hz 7.5W 160gph (600lph) 53" 3.5" L x 2" W x 3.00" H
MP900 120V/60Hz 8.5W 230gph (870lph) 46" 3.5" L x 2" W x 3.25" H
MP1200 120V/60Hz 20W 295gph (1110lph) 69" 3.5" L x 2" W x 3.25" H


what is the right amount of flow. I have a uniquarium with the rio pump that came with it and one smaller power head.

suggestions please.

Flow all depends on what type of corals you have, if you have a reef. Otherwise I would see what flow the other power head put out and match it as close as possible with the new one.

the corals that i have are as follows:
Green Frogspawn
Green Candy Cane
Green Star Polyps
Brown Star Polyps
Zoanthids
Mushrooms (Green Hairy, Melon, Blue pimpled, blue stripped, green ricordia, blue)
Xenia - waving hand
Galaxia

no way of knowing the other flow, it was given to me from a buddy, don't even know what kind it is, but it works quite well. just want to put one more in to replace the one i broke.

I myself depending on where the power head is placed would go with the MP900. The corals you have like decent flow, and that on should do the trick.

are maxi jet's alright?

the mp900 is $16.95

any powerheads that are better that are too expensive?
