kendaroo Posted June 21, 2010 Share Posted June 21, 2010 How hard is it to seal off the bottom returns on an acrylic tank that's plumbed for a closed-loop system? We saw a tank with dimensions I liked today, but it had more holes in it than I would want to use. (Actually, Woody told us we didn't want all of those holes. Glad I asked! (whistle)) Advice? Thanks!

Emerald525 Posted June 21, 2010 Share Posted June 21, 2010 Why don't you leave it as a closed loop system? Quote Link to comment Share on other sites More sharing options...
tanktop74 Posted June 21, 2010 Share Posted June 21, 2010 Closed loop systems are one of the things Woody is against. From what I have heard from others, this helps increase your flow in the tank, reducing the need for additional Powerheads in the tank. If I had it to do again I would go closed loop in a heart beat. Did he talk you into a plenum too?? lol Its best to get more than just Woodys opinion and then make your own decision, there is more than 1 way to skin a cat!!! Or plumb a tank!!!

Chief Posted June 21, 2010 Share Posted June 21, 2010 When I did my tank, I did not want to do the CL through the bottom. I ended up patching 6 holes in the bottom and putting 12 holes in the back. Here are some pictures. Jay Quote Link to comment Share on other sites More sharing options...
kendaroo Posted June 21, 2010 Author Share Posted June 21, 2010 Well, then I'm glad I asked again! (laugh) Tell me more! Have any good resources for learning how to plumb a system? I have a lot to learn still! Sumps and skimmers and closed loops, oh my! So, is this a dumb idea? The tank is a TruVu, in good condition, and it's 72 x 18 x 20. I like that it's long and shallower- I might be able to reach the bottom! Pros/cons of going this route? There was a skimmer with the tank, but I don't know anything about it. SeaClear brand? Sump was too small. I'd probably just get the tank only. Quote Link to comment Share on other sites More sharing options...
kendaroo Posted June 21, 2010 Author Share Posted June 21, 2010 Jay, that looks amazing! So, don't fear the holes in the bottom, huh? Gillian Quote Link to comment Share on other sites More sharing options...
Chief Posted June 21, 2010 Share Posted June 21, 2010 To repair the holes in the bottom, you will need some Weld-On #4 ( you can get this from Tap Plastics or Online ). An Applicator: Set your patch piece on some sewing needles, squirt the Weld-On #4 under your patch piece with the applicator. Make sure you have good coverage and pull out your sewing needles. The Weld-On actually "melts" the pieces together. Mine have been holding since May of 2005, no leaks. Jay Quote Link to comment Share on other sites More sharing options...
