hey mar-y-sol i too have a 29gl display and 10gl fuge, i use a maxijet 600 right now but i'm gonna go with the maxi-jet 900 here soon i think its just about right. Are you running a skimmer in your fuge? I put my coralife SS65 down there it really is a great system all together, although i hear octopus skimmers are better. Are you useing a siphon overflow w/ box?

Karl, I'm not sure if you want a pump in your refugium. There should be very gentle flow through it, usually fed from a T off your main pump, if it's seperate.
Ehiem 1250. It should be next to perfect, I am redoing my sump return and refugium pump set up. Well more like plumbing all together because I was kind of cheap to get a really good pump.
I would REALLY advise you to get a 20g long or 20g in general. Not sure but I think I read another thread you made and you had a Remora Skimmer?

I like mag pumps, if you get the smaller mag 1 or 2, they are very quiet.
Hi guys, thanks for the advice, here is some of the problems I am encoutering. I am just putting just a refugium no sump so I need a pump big enough to get it to return to the main tank which is about 4-5 feet higher than where the refugium is going to be. A maxijet wont lift the water that high and if it does I wont get the minimun 300gph that I need, I think the smaller mags will do the same. I was looking at a mag7, I found it on petsolutions for about $60 plus a wavemaker so I'll put two returns one on each side. I am thinking of using an overflow box, I found one that does 600gph, will this be fine to use a 600gph overflow with a pump that returns ~400 gph? I dont see the problem but I've never set up something like this. I also wanted to see if anybody has 10gal or 15gal they had laying around and is willing to donate it to my little experiment. Thanks for the help, Karl
Karl, I used the RC calculators and came up with around 370gph through the 2 returns. This is based on hard plumbing.

Due to the fact that the tank will be a refugium ONLY, I would do it because the flow going into the tank will be fairly quick which means it will kick the sand around as well as whatever is in there. If you want flow then use POWERHEADs inside of the tank.
Maxi-Jets IMO will not push enough to return the water back up to the display. I tried with a MJ900 and it went no where, in fact it was struggling to get to 3.5 feet is even that. Stick with something that will return around 100-150gph at most. Eheim 1250, Mag 3, Queit One 1200, etc. Basically anything that puts out around 300gph and can handle 4-6ft of head will be ok.
Remember you are trying to:
1) Have no microbubbles
2) Low flow because it is a refugium after all (3-5x the display) - the water needs to be able to stay in the refugium for the macro plants to absorb the nutrients which the display tank algae is fighting for.

Yeah that sounds good, remember that the most pump stats are at 0" head as you go up and split the return you will loose some pressure thus will transfer into GPH but it will not be a lot.
The overflow is perfect, they will usually handle more than they are rated for but with less flow they are really quiet.

Karl.......Ok what I did with mine is "T" off the main pump.MAG7..and ran the pluming under the sand bed with 45's in each corner which makes the Cheato tumble in the center of the fuges.....the 45's are adjustable in different directions.....
BTW its still clean becuse the has only been up for a few weeks
