i use two pumps on my sump. i use one for one side and one for the other. i like doing it this way so if one goes out then i can still run the sump.
Anyone use 2 pumps on their sump?

I was running two quiet ones 4000 and switched over to a single 2000gph pump. Now I regret it, had it go out while at work and heater was still going, cooked my bio in the sump. I liked the redundancy of the two, if you can keep the power cost down

I have a single overflow box on my 220. It has 2x .5" and 1x 1" holes (total of 3 holes). I currently run a mag 9.5 because i was told this is what my single durso 1" drain could handle by my lfs. I got my hands on a brand new mag18. well I hooked it up and my single drain easily handled the mag 18 @6' of head. It was obviosly loud but it kinda throws all the flow charts out the window. as soon as I build my new sump I'm going to run 2 mag 9.5's or 2 mag 12's, not sure yet. I love the idea of dual sump pumps
I agree. The Laguna Max-Flo line of pumps is awesome. Their efficiency blows the mag drive pumps and pretty much every other pump out of the water (pun intended). If anyone is in the market for a new pump, definitely check the Laguna's out.
I am set to run to two Mag 18's on my 600. I also like the idea of having two pumps in case one fails.
Wish I knew about the Lagunas....

If you are able to return those Mag 18's, I would do it. I ran the numbers real quick for a few different scenarios. I assume 5' of head height and that you pay the national average for electricity of $0.11/Kwhr. I pay $0.34 at the highest tier (which my tank pushes me into), that's why I'm so obsessed with making sure I'm running the most efficient equipment possible.
The most efficient way to go would be running only one Laguna 2900 that pushes 2,400GPH at 5' of head and only draws 130 watts. Buy 2 so that you have a spare on hand in case the first one craps out on you.
Below are the numbers; you can see that running one Laguna 2900 will push more GPH at half the cost of running two Mag 18s. Bottom line, you save $152.07 per year if you swap out the Mag 18s for the Laguna 2900. If you like the idea of running 2 pumps, (which I totally understand) you would still save quite a bit of cash going with 2 Laguna 1500s.

Danner is going to have to step up their game in order to have any chance at competing with these Laguna pumps.
I moved back with my parents and dont pay the electric bill =P
next pump i get will be a laguna, but ill stick with 2 mag 18s for now b/c i already own 1 mag 18.
