OK, I think I'll do that. 1" pipe is a lot easier to work with, and I would have more room in the overflow box for standpipe modifications to quiet noise. It looked like they had a lot of data on the WetWebMedia site, so I assumed it was good. No one seems to agree with their numbers though...

So this is for a 75 gallon tank with a 50 gallon sump and a 20 gallon Fuge. The overflow box is 6 inches deep by 10 inches wide. I've heard some mixed things about drain pipe diameter. I designed my system using this page: Bulkhead Flow Rate Art where they tested overflow boxes with a lot of...

Hey guys! I've purchased all my plumbing parts and am about to assemble it. I wanted to post my plans up here first though to see if there were any newbie mistakes I was making in the layout. My sump tank sits on a shelf extending 6 inches out behind the back of the...

hmm, not sure why formatting went crazy in my last post, but doesn't seem fixable. Here are links, if they will work: pan world 50xp-x (90 W 1100 gph) Pan World Magnetic Water Pump danner mag drive supreme 12 (1200 GPH 110 W) Danner Mag-Drive Supreme Water Pump Eheim 1262 (900 gph, 80 W)...

Hey Steve, Moving onto my return pump now. I've narrowed it down to a couple of choices, but wanted to see if you had any advice, or brands you like. I have an overflow box with a 1.5" bulkhead, which should deliver about 800 GPH from tests I've found online. I was also thinking about adding a...

Hah, yea, right? So I think my current plan includes taking the refugium out of the sump and having a large return tank (just losing the refugium baffles, leaving the other baffles in place) and I am going to build a second small stand for a 20 gallon (tall tank I think, that I have in my...

OK, I think I'm going to change the plan and ditch the refugium in the sump. I'll add a separate 5 gallon one to a shelf on the side of the main tank. That will give me a lot more room for the return tank, and overall make my life easier I think. I'll just gravity feed the refugium by...

OK, gotcha. Good point about depth of the return, didn't think about the syphon during a power outage. Probably would have flooded myself in the short run on that one thanks to seattle's crappy power. So the valve I put in serves the same purpose as an inline valve (ristricting water to the...

OK, gotcha. If you slow down the intake but not the return, wouldn't you run into problems where the sump return tank runs dry? I figured if you turned one down you would need to be able to turn the other down also. Maybe I'm confused. I just recieved my overflow box that was SUPPOSED to be 600...

The diverter on the return is to allow me to regulate the flow of the return. It lets me return some of the water being pumped back to the sump tank instead of to the main tank. I guess the idea here is to be able to lessen the return flow without putting stress on the pump (which just putting...

Hello all, I'm pretty new to this forum and just starting up a saltwater aquarium after a long break. I've been doing a lot of reading online (thanks to many of you for some very helpful links!), and I think I have finalized my sump tank design. I wanted to post it here for you guys to see...
