ChrisQ Posted April 30, 2018 Share Posted April 30, 2018 Or is there a better choice? https://www.amazon.com/Black-Aquarium-Silicone-Sealant-Cartridge/dp/B00EZB2MDI/ref=cm_cr_arp_d_bdcrb_top?ie=UTF8 Quote Link to comment Share on other sites More sharing options...
ChrisQ Posted April 30, 2018 Author Share Posted April 30, 2018 I know some versions at Lowes/Home depot are good for aquarium use but what would be best especially for acrylic to glass? Quote Link to comment Share on other sites More sharing options...
pdxmonkeyboy Posted April 30, 2018 Share Posted April 30, 2018 there is no good silicone that will stick to acrylic. It works sometimes for baffles, sometimes they just work loose. acrylic is just a very oily substrate for things to chemically bond to.

Flash21 Posted April 30, 2018 Share Posted April 30, 2018 (edited) If this helps you out any? I used the black aqua crap from Amazon. I made sure to use a fat bead and to make sure both surfaces had plenty on. I even back caulked it just Incase for the stair step. Almost all All In Ones use the same concept. So I’m sure if your doing something like that you’ll be fine. If your using on baffles and or to create a AIO I suggest to have the plexi at least 3/16” short overall so it can kind bond to the butt end of the plexi to the glass Then you can do opposite side as well. So it has three points of contact if possible. Edited April 30, 2018 by Flash21 Quote Link to comment Share on other sites More sharing options...

Just make sure to seal everything and let it cure for 24-48 hours. Quote Link to comment Share on other sites More sharing options...

Yes, inside the tank.(small cube and very small box) Only concern i have is getting the best silicone i can get. The maker of the box made it in a hurry and out of spec and the bottom panel is paper thin(about 1/16th) so its a concern to get a really good seal all the way around the box and aquarium safe of course. Just wasn't sure if the silicone for aquarium use is any better than what we can get at Lowes or Home depot. Quote Link to comment Share on other sites More sharing options...
