Martin McNally Posted July 11, 2008 Report Share Posted July 11, 2008 I need to make a overflow box not an actual CRP over flow but you know the acrylic that ususally goes in the corner of the tank with teeth on the top. Anyone know where I could get some black acrylic to make it or another alternative? My hole with be in the back of the tank rather than the bottom so it doesnt have to go all the way to the bottom.

sharuq1 Posted July 11, 2008 Report Share Posted July 11, 2008 You could make it with glass. The teeth aren't needed, and impair the skimming action of an overflow due to the meniscus on the water. If you are concerned about fish going over the overflow, just put in some light diffuser at the top or add a screen/foot to your intake. Silicone seems to adhere much better to glass than it does to acrylic. I looked for black acrylic in town but did not have any luck. Black glass was ridiculously expensive. However, if your overflow is small--go to the Habitat for Humanity Restore--I noticed they had some tinted glass there last time I was in. It was too small for my project, but it would work for a smaller one. The glass from one of those retro 70's glass coffee tables would work great. We just finished making a tank-long overflow at the back of our tank. Waiting for the glass was a pita (as we needed almost 4' of it), but making the actual overflow was easy. Will post the link to that build soon as I update it with pictures. Quote Link to comment Share on other sites More sharing options...
Martin McNally Posted July 11, 2008 Author Report Share Posted July 11, 2008 Your right that sounds like it might be better and way cheaper since I already have glass. It just doesnt hide the plumbing, but I think i ordered black fittings anyways. Martin Quote Link to comment Share on other sites More sharing options...
sharuq1 Posted July 12, 2008 Report Share Posted July 12, 2008 Here is what we did. It's not really a detailed description. my tank We did a run with tap water and the overflow worked. Nice thin skim of water off the entire length of the tank. Quote Link to comment Share on other sites More sharing options...
Martin McNally Posted July 12, 2008 Author Report Share Posted July 12, 2008 Just found this http://www.mops.ca/cgi-bin/SoftCart.exe/sk...e8c8+1215852066 Might be a winner for me. Will wait until the bulk head fittings arrive to see if it would fit. However chop one end of that thing and it would be perfect.

sharuq1 Posted July 12, 2008 Report Share Posted July 12, 2008 If you have a small tank, that's not a bad idea at all. They even sell those at the lfs. Quote Link to comment Share on other sites More sharing options...
