what return pump to use with 1200gph overflow?

  • We are currently upgrading MFK. thanks! -neo
Just do the 1200 so you have headroom later on. If you throw 800 gph at it (or a 1000), its not going to affect anything. I honestly think you are better this way.

And not to poo poo on anyones feelings. I like Mag pumps for submersable applications. They are extremely reliable, but, the bigguns like the Mag 18 dump a ton of heat into the water. If it were me, I would do around 1000 gph and make up for the loss in flow with slightly stronger powerheads.
 
so u think i should do a mag 18 and a 1000gph overflow? or even the via aqua 4900 and a 1000gph. i know the mags are better pumps. i plan on 2 1000gph koralias for powerheads. no plans for a wavemaker at this point.

You should do the 1200 gph overflow. Better to have that extra flow to play with. With the 1800, you really won't have to dial it down much, if it all based on your plumbing. Definitely won't have to turn it down 25%.

If you were to do a smaller overflow, upping the powerheads is a good idea(I really think it is anyway, Koralia 2's that are at 950 gph I think won't do a whole lot for your system, go with the Koralia 4's moving 1400 each). It doesn't replace that extra flow going thru the sump, but does help. Ideally you want as much flow as possible to go thru your sump so that it can be filtered. Powerheads do not do this, though they contribute to keeping everything suspended and highly oxygenated.
 
NEVER try to match or go over the limit gph of your overflow box, it will overflowed eventually. If you have a 1200 gph overflow box, IMO 1000gph pump is good enough.

This has already been talked about in the thread. It is easy to put on a valve to prevent this. Also, a 1000 gph pump is going to be pumping somewhere in the range of 500-600 gph when head height and plumbing are taken into consideration. Then you are just wasting the overflow box you have.
 
i always like to go over the gph of the overflow box. if your pump is too undersized the water level of the internal box may be too low and your overflow can get air bubbles in it. i just use a ball valve to maximize overflow box.

i ordered the 1200 gph box and mag18 pump. mag 18 is on sale at dr. fosters for $136.00 .

all i need now is 2 1400-gph powerheads, skimmer( most likely going with asm g2 skimmer) and phosphate/carbon reactor. .

great lakes aquarium emailed me the price on the 165 tank. 72x24x22. price includes 36" stand, sump/refugium, built in 100gph overflow, return pump w/all plumbing, reef dynamic 180 skimmer, fuge light, sliding glass tops for tank. $2000.00 shipped. might have to stick with my 125.

Agreed. Yes, great price on Fosters currently. Same with the powerheads actually. The Two Little Fishies Phosban phosphate reactor is priced the same pretty much as everywhere else too. You could get it all at once.

Yes, stick with the 125. You can find a better setup than that for cheaper if you are patient. I don't like the all in one setups, the equipment isn't always the greatest and you then can't personalize your setup as much.
 
I dont like calcium reactors, because you will eventually need to dose lime water to counteract the pH drop that comes with the calcium reactor. Granted, thats only when you calcium reactor is putting out a lot of effluent to keep up with a heavily stocked lps or sps tank. I would rather do two part.
