    Return plumbing question

    Right now my main issue is just using the single Mag 12. I have a 29 gallon sump and I plan on upgrading to at least a 55 when I find a good local deal. I'd just like to run the returns to both overflows with one pump. I'm making rocks for the tank as we speak...and while they are freshwater...

    Return plumbing question

    Thank you Don. I'll swing by the local Lowe's and see what they have. I have plenty of Sch 40 1" and 3/4" pvc in the shop to mess around with. I do plan on using the correct valves and unions in the system so I'll see what I have local. I appreciate all your patience.

    Return plumbing question

    So I should run 1" line to both return bulkheads? The current fittings are approximately 3/4" according to my calipers. Would I put a 1" to 3/4" reducer right at the bulkhead? And again my return hoses are 1" in diameter. I assume I can get a fitting that will attatch to the 1" fitting to...

    Gravity fed skimmer question

    Well I also have a Mag 7 pump to drive a skimmer if I can use the Mag 12 to feed both overflow returns on my tank.

    Return plumbing question

    I'm new to plumbing in general. We had some additions to our home and I have a ton of PVC laying around. I had proposed to run a hard straight drop from the overflows into the sump with a 90 to the sump and a 90 down on both. The return from the pump would be the same basically. I've...

    Return plumbing question

    Thank you for all the help Don. I'm new at this and I'd really like to get the thing plumbed correctly the first time. Especially if I can reserve the Mag 7 to drive a decent skimmer. I'll see if my local Home stores have Spa Flex. Is it known by any other name?

    Return plumbing question

    Well it's clear flex hose on the overflows to the sump. And it appears to be 1" ID. The flex hose going from the pumps is smaller and is black and flexible. Sort of like a rubber type hose.

    Return plumbing question

    For water out of the overflow to the sump it appears to be 1" in diameter. The return lines on the Mags are a tad bit smaller so I would guess that they are 3/4" in diameter.

    Return plumbing question

    I planned on doing some hard pvc plumbing for it. Right now the Mag 7 is connected to the return on the short side of the tank. The head is probably 5' maybe using flexible hose. The Mag 12 is on the same side of the sump as the 7 with flexible hose running to the far return with a head of...

    Return plumbing question

    Don, I roughly measured the overflow boxes and they are about 6" x 10" rectangles in each corner of the back of my tank. I believe I have 3/4" return lines on the pumps and 1" on the overflows. I don't really know a bunch about flowrates, gph, etc. but I'm thinking a Mag 7 and Mag 12 together...

    Return plumbing question

    I have aquired a 185gal reef ready setup. The sump is about 30 gal and has a Mag 7 and Mag 12 connected to the returns. The tank is dry now as I plan on doing some hard pvc work before I get it percolating. My question is do I really need both of those pumps? One on each return or could I...

    I meant to add that I used 4 parts oyster shell to 1 part type III portland cement. Mixed it till it was about like cottage cheese consistancy and put it in my mold. I let them set up overnight...at least 24 hours. Then take them out and wash the loose stuff off. Mine seem to get a tad bit...

    Gravity fed skimmer question

    roscoe, What I was thinking was instead of a recirc I wanted to feed the water straight from the overflow to avoid another pump and another source of heat (as well as electrical connection). But if I can use a feed off of my Mag 12 pump to drive it then that would be great too. It doesn't...

    Gravity fed skimmer question

    I don't have a skimmer for my setup as of yet. I thought I might be able to build a simple one and feed it with one of my overflows. I figured I needed both pumps as that was how it was setup when I bought the system. It was dry and out of the previous owner's home and so I didn't see it...

    Gravity fed skimmer question

    Thank you all for the replies. My significant other and I have purchased a complete system from our LFS. I'm currently making oyster shell/concrete rock and was considering giving a go at a diy protien skimmer. I know I have a Mag 7 and Mag 12 but I don't know the flowrate on the tank as it's...

    Gravity fed skimmer question

    Thank you MC...I will check on that particular skimmer if it's working for you! Would it be possible to step down the diameter of the return line to the skimmer? Would this increase the velocity of the water flow into the skimmer or does that matter?

    Gravity fed skimmer question

    I have a 185 with overflows on both sides of the back. One return has a Mag 12 and the other short run has a Mag 7 return pump. Would it be possible to have my short return overflow run to a skimmer? Since gravity is reasonably free I wondered if this would be a possibility? :)

    I've been making diy rock for about a month now. Here are a few pictures of my first batch. I'll try and get some pictures of the batch that's soaking as well.
