reefgeek84 Posted November 2, 2006 Share Posted November 2, 2006 silicone, is suppose to be the best, but they do not attach well together...because the silicone, does not stick very well to acrylic.... Quote Link to comment Share on other sites More sharing options...
R-3 Posted November 2, 2006 Author Share Posted November 2, 2006 Do you know what kind? Later Ryan Quote Link to comment Share on other sites More sharing options...
impur Posted November 2, 2006 Share Posted November 2, 2006 100% silicon is what you want. Scuff the acrylic where the silicon will attach to it. You will be fine, the pressure of the water will help keep it in place too. Quote Link to comment Share on other sites More sharing options...
R-3 Posted November 2, 2006 Author Share Posted November 2, 2006 So any 100% silicon will work? Doesnt need to be aquarium stuff? http://www.reefcentral.com/forums/showthread.php?s=&threadid=912378&perpage=25&highlight=ocean%20direct&pagenumber=2 How about that stuff? About half way down. I think thats what Ive seen my LFS use is the GE stuff. Later Ryan Quote Link to comment Share on other sites More sharing options...
impur Posted November 2, 2006 Share Posted November 2, 2006 Yep thats it. Silicon I or Silicon II i've used both. Quote Link to comment Share on other sites More sharing options...

H20cooled Posted November 3, 2006 Share Posted November 3, 2006 Ryan, Just make sure that it does not say anything about mildew control or anything like that, they have an anti-fugus additive in them and it can harm your tank. The Type I for Doors & Windows seems to be the one to get. Quote Link to comment Share on other sites More sharing options...
Ronjunior Posted November 3, 2006 Share Posted November 3, 2006 Here's an article I bookmarked for gluing glass to acrylic. Bostik Titan Bond Plus....towards the bottom of the article. http://ozreef.org/diy_plans/techniques/gluing_acrylic.html Check the MSDS sheets from GE for their Silicone I. http://www.geadvancedmaterials.com/geam/gesa/Residential/en/Products/ProductsLanding/products_landing.html. Might e-mail or call their support to make sure it's not mildue resistant. Some say 100% silicone, yet they put the additive in there...hmmm...101%?

H20cooled Posted November 3, 2006 Share Posted November 3, 2006 It's pretty easy to tell which one have the additive and which ones don't, just look for the mildew resistent symbol on it. Quote Link to comment Share on other sites More sharing options...
Guest Mbeef61 Posted November 3, 2006 Share Posted November 3, 2006 how i glued my acrylic bulkheads to my glass sump was too sandwhich them with glass strips...attaches to glass nicely....i made it that way so they are removable and i am able to adjust them. i imagine that would be nice to dial in an overflow Quote Link to comment Share on other sites More sharing options...
R-3 Posted November 3, 2006 Author Share Posted November 3, 2006 I was wondering since Im gonna use black acrylic and have a black back is there 100% Pure SIlicone that is black? Does GE make a black? I just thought it would look nice. Later Ryan Quote Link to comment Share on other sites More sharing options...
impur Posted November 3, 2006 Share Posted November 3, 2006 Yes there is black silicon. You'll have to do some looking around more though. I used the mildew resistant silicon for the baffles in my sump. I used the other for gluing together my external overflow. That was 2 years ago. Neither has been a problem FWIW.

Later Ryan I have an extra brand new, never been opened 10.3 oz tube of All-Glass Aquarium Black 100% Silicone I'd be willing to trade for a polyp/frag or something. PM me if interested and I can bring to the Nov. meeting if you'll be coming up this way on that Sunday. Quote Link to comment Share on other sites More sharing options...
R-3 Posted November 3, 2006 Author Share Posted November 3, 2006 I appreciate that Ron but Im gonna do it tonight. I hopefully will have the tank up and running fully by the start of next week, hopefully. Ill try to find some black silicone, if not ill use some regular stuff. Is there a trick when applying? Ive done a lot of caulking so I think I should be okay. Later Ryan Quote Link to comment Share on other sites More sharing options...
WAVES Posted November 3, 2006 Share Posted November 3, 2006 I would recommend Perennator silicone from Custom Aquatic. Its this german stuff that works amazing. Quote Link to comment Share on other sites More sharing options...
R-3 Posted November 3, 2006 Author Share Posted November 3, 2006 That stuff is backordered. Im gonna try HD tonight and see what they got.Later Ryan Quote Link to comment Share on other sites More sharing options...
