    Return Pump

    Afternoon,
    Someone is selling a Mag 12 return pump on here and i was wondering if that is an acceptable size for a 200G tank?

    I would say yes, provided that that is not the only flow going on in the tank.

    Yeah that's 1200gph with 0 head so it would be probably around 1000gph on the tank. That means that it's turning the tank over 5x per hour which is good flow for a sump. Use power heads to increase water movement in the tank itself so that you are not increasing flow in the sump.

    Murf, I don't have a sump for it yet. Still trying to connect all the pieces one at a time. This was JJ's old 200G bowfront. I just bought an Apex system so i am working from the list that he gave me to piece meal together. I think i need something a little bigger than the Mag 12 since it would only push through about 1000 gph in the tank.

    I agree with the mag 18 as well, it just depends on what you want or how you want to utilize your sump. I am not doing a fuge in my sump and I have a ton of ceramic media along with a bio pellet reactor and skimmer so I am not really looking for a slower flow sump, but most people want to do a fuge and with that slower flow would be good. Dual returns would appreciate the increased flow from the mag 18.

    Are you going to use a Sump? If you are, you need to make sure that you get return to the sump what you are pumping up to the tank. Using a Mag 18 is a waste, if you are only draining 1000 gallons per hour into the sump. Marry the return pump to the drain so you don't have to spend extra $$ on a pump and then throttle it back down to what a cheaper pump costs.

    Glad to see you are taking your time and asking for advice instead of jumping into such a big tank.

    Alot of this decision will be based on your sump size which is what hooked, murf and levi are hinting at. A larger sump with no fuge means you can have a higher turnover rate (equals more polished water faster). Measure the interior of the stand and find out what size sump you are going to run first. Once you have the size of sump you can determine the sump layout and mechanical/biological filtration you would like to run. Once you have your schematic you can figure out your correct flow rate through your sump and adjust your gameplan on what your flow will be in the dt based on which return pump you decide.

    You could also use a mag 18 and utilize the unused power to feed an inline skimmer and reactors, thus saving you money on your electric idea by running less small pumps.

    Look into dc pumps as well which are a newer gadget to the hobby that will last longer and save even more money o your electric bill

    Hey JJ! didn't know you were back!

    Welcome back!

    I want to take my time and do this one right with all the right equipment. or at least as close to what i can afford. I did buy an apex system so ultimately i would like to tie as much into that as possible. This was your tank, what size sump do you recommend? : )

    JJ isn't back. He just found some wifi somewhere. He also had that tank tied into his system so the sump was 2 180g tanks. You could get by with a 75 gallon tank. It would be better to find an old 90g and build a sump out of it. I can help you build it if you find a tank.

    Wow. How long has this tank been in the club. I helped levi move it from the last members house.

    I think it came from Denver in early 2012. I know of 5 owners since then.

    Acrylic or glass. Either will work. I'm using a 55 under my 180. Wish it was a little bigger though.

    I think it might be a 75, here is a pic an employee sent me. I asked for the dimensions so whenever they text me back we will know of its a 75 or 90.
