Stick with eheim over mags. eheims last a lifetime

yah i've heard that mags had problems with their screws rusting or something...i dunno if they fixed that yet

not sure but i think mags run a little hotter too

dont forget to add in the head loss due to turns. Use the head loss calc on the front page to get a better idea of how much loss you will have in the return. Then you can make a better decision on pump size.

yellow is for the 1250,

the smaller 3 pumps don;t use much power so they don;t handle head loss very well, anything over 5 feet i would recommend the larger 1260

Thanks everyone... so confusing!

I don't think there is anything else besides the 1250 or 1260. If the 1250 is too low, the 1260 to me looks like it's much too strong.

With the Mag 5.. it should do everything right? A little slower in the sump is good for the fuge and to give more contact with the skimmer?

From what the chart reads, it looks like at 4ft it will be roughly 190 gph. Does this sound right?

I agree Eheims are great pumps, but you gotta get the right one!!! The Mag 5 is a sure deal at this point.

I don't know!!

 

[neotekz]

the 1260 will be good for your setup since you are getting a larger sump and you can always divert some of the return flow into your sump or just put a valve on the return

Neo: the 1260 says 635 at 12'1".. but I can't find what it would be at 5 feet.

I"m trying to avoid that.. since I already have a mag 9.5 now which is too strong. If I was going to divert it back I would just keep the one I have now. Trying to avoid more plumbing!

At twelve feet both pumps are zero flow. At 5 feet the flow looks like its around 350 to 400gal for the 1260.....thats how I read it anyway

 

[neotekz]

i know what you mean, using a valve to restrict a pump seems kinda counter productive. for $50 the mag 5 does look very good. my mag 7 ran without any maintenance or problems for almost 2 years until i upgraded tanks. i do like how they are small compared to the eheims

1250 is plenty actually... it will do about 200gph with your setup... dont forget, the height calculation for head-pressure is done by measuring the difference between the two water heights... which is more like 3-4 feet in your case. All you need for turnover in your sump is about 1.5-2x the tank volume per hour... so 200gph is plenty. You can get a majority of your flow from powerheads and closed loops in the tank itself.

it goes from 0 to 635 with no increments in between so it's a little hard to tell what the flow would be at 5 feet. go down from the blue line at 4 to 6 feet and then you have to estimate. i would guess that 7 feet probably gives you half the flow of 635 so 5 would be around 400. again these numbers are just estimates and i have no idea how accurate these are with each pump...

so the height from to top(waterline) of the sump to the top of the display?

 

[hahnmeister]

I would also suggest the Oceanrunner 2500 as a potential pump.

Why dont people use Quiet Ones? They are about as quiet as a Mag-Drive... thats why.

Ok, here's what I gather. The 1250 is roughly 185gph and the 1260 is 400+ by the chart. Either pump really isn't falling in the 3-5x rule you are aiming for. Even with plumbing flow loss, the Mag 5 is looking real good right about now.

 

[NanoGurl]

Thanks everyone. I'll just go with the Mag 5. That will def work and it will fit in my small return area better then the Ehiem. Maybe when I build the new acrylic sump I can upgrade it then and use the Mag 5 for something else later on.

Monday Tank Update!

Well, back on topic for the tank itself.. today was a huge day for the tank. Since all levels were testing good, we decided to go ahead and transfer over all fish and corals from our other two tanks. We transfered over some of the LR as well, and put the rest of it we didn't use in the sump.

I'm working on resizing the photos right now and will post some shots in a few.

Thanks again for everyones help and opinions tonight!
