Pumps For 55G. To Eliminate Powerheads and can you also.....

Regulate the flow on them using ball valves? I am trying to eliminate the PH in my tank and use a pump. I wanted to know what is powerful enough for a reef and also can you regulate flow with ball joints? Will it damage the pump? Thanks

Yes, you can restrict the flow OUT of a pump with ball valves. The general rule of thumb for tank throughput on a reef would be 10-20x water volume in turnover per hour. You also have to take into consideration head loss through 90* angles, Ts, Ys, etc. You'd probably want something along the lines of a Mag12 which would push 1200 straight out of the pump but by the time you get done bending it around it would probably be closer to 700gph. I'd probably go with an 18 and dial it down if need be.

Thanks for the info but what do you mean by a 18? Do you mean Mag18? also the previous post what do you mean by a 9.5? Any suggestions on where to order these from??

I am looking into Live Aquaria. I see the Little Giant that states gallons per hour for a 3,6, and 12ft. I do not understand what these sizes mean. Also I see the MAG MD18 with 1800 with a 21ft. max head 145W and a 3/4 fittings. Question how easy is the maintenance on these? Thanks alot for info.

Mag 18 (1800gph), mag9.5 (950gph).

The GPH readings are at 0 head. That's pushing straight out of the pump. The ft height is how many verticle feet (head height, see calculator that I posted) the pump could push up and by the time it got to the top of that run, the posted value is what would be coming out of the other end (at 21' with 3/4 fittings a mag 18 would be pushing 200gph, for example).

If you take your desired pump and enter the information into the calculator that I posted you'll find out how many GPH will be coming out the end of the pipe.

Have you checked CaptiveReefs? I've had a hard time beating his prices on most items.

I would be doing the same setup as in http://www.melevsreef.com/closedloop.html except this is for a 55gal not 29gal. So would a Mag18 be powerful enough? the pump would be on the floor and 4 feet to the top of tank and also the tank is 4ft wide so it will split to 2 feet on each side. The setup will be the same as his except with ball valves. When I entered it into the calc it said 668gph when all is said and done I think I did it wrong.

I was wondering if a more powerful Pump like the MD24 would be better I can always control them and make more outlets?
