KnineDHP Posted April 15, 2022 Share Posted April 15, 2022 Is this acrylic tank toast? This is a bottom seam near the front right corner. There are a few of these this is the largest. Is there a fix? I don’t know if it leaks I do t want the seam to have any moisture in it if it can be repaired. thanks for the advice. Link to comment Share on other sites More sharing options...
Cypher Posted April 15, 2022 Share Posted April 15, 2022 Put the tank in your bathtub or shower and fill it up about half way (with a gallon jug) and let it sit there to see if it is leaking. If it is leaking you can go around the seem with Aquarium Safe Silicone (https://fishlab.com/aquarium-safe-silicone/). If there are no leaks, you can take a torch to the edges to clear them up.

lefty o Posted April 15, 2022 Share Posted April 15, 2022 i might try to find some acrylic glue, and wick into the crack, then after it dries run a bead of silicone over it. Link to comment Share on other sites More sharing options...
Anon Posted April 15, 2022 Share Posted April 15, 2022 Wait a second! Silicone doesn't bind to acrylic. You're going to need something like liquid acrylic or acrylic glue. Google "acrylic aquarium repair," it takes a bit of prep work and the right materials. Link to comment Share on other sites More sharing options...
eatyourpeas Posted April 15, 2022 Share Posted April 15, 2022 (edited) You can use acrylic welding chemicals to fix it. Weld-On 4 is very thin and can get in the space that is showing the gap. Once that is done, you can caulk all the internal seams with Weld-On 40. Do not use silicone as it will not bind to the acrylic. I built my SW tank using both of those and it worked out great. It is almost 4 feet wide, made out of 1" acrylic. And no, I do not clean the diatoms because the critters get very unhappy if there are none to eat.

xXInkedPhoenixX Posted April 16, 2022 Share Posted April 16, 2022 TAP is amazing, there is so much they are able to do. Specifically for aquariums, I've had them cut me pieces for replacement glass lids. Link to comment Share on other sites More sharing options...
