Tank repair

[Reefrookey]

I have a chance to purchase a 300 gal tank that has a split seam on one of the end panels. Its is the vertical seam near the top were the side joins the front viewing panel. The side panel butts up to the front viewing panel. I am not sure how far down the split extends.
I was wondering what you thought about injecting this seam to repair. Is it plausible? I have worked w/ acrylics enough to feel comfortable with building varius projects as well as the sump under my sixty cube 22.75 by 22.75 by 16 tall. I also have all the wood working tools (proffesional grade) i would need to cut down and reutilize the acrylic for a smaller size tank. the dimensions for the tank are 96"x24"x30". Thanks in advance

Inject it with Weldon 16. Let it set overnight. Then, make a "chamfer" strip to run up that corner on the inside of the tank and glue it in place to help strengthen the joint. You will see the joint but it will hold. Just make sure you run that chamfer strip from top to bottom.

Welcome to TRT! I think your saying it's a Acrylic tank?Ussaly unless home made it'smolde at that size tank,but either way ,I'd take panle totally off and clean,prime and reglue(or clean recauk(if glass) ).

[lagrew]

yeap you got it, i would take it apart, then clean strip redo if glass, otherwise weldon 16 will work and run a strip from top to bottom that would definitly do it.

[Reefrookey]

The tank is acylic. so taking it apart is not an option.

Any chance you could attach a picture to this thread? I'd be more inclined to cut that side off and reattach the entire thing. If you're good, is may only mean an inch or so of shortening on the tank, and you could fix it with a seamless weld.

I would not try to fix that seam with anything. It's too hard to get in there to clean out the old pieces of acrylic. You need a smooth surface to have a good bond. The last person that built it didn't have a good smoth joint to start with.

I would cut it down to make a smaller tank, cut it on the table saw, then clean up the joints on the router.

I don't know, I think if you did take your time and clean the surface and do like Randy said it may work very well, Then do the same on the outside corner also. I know if it was my tank I would give it a try, The thing about acrylic if you clean and glue and make sure you have a good fit, it is strong. When I glue I can usually tell if I have a good bond if I see no cloudiness in the piece and it is clear at the weld. JMO

For a perfect repair, cut it down, for a repair that you don't mind seeing, go with the repair as randy suggested. The best solution in the end would be to cut it down IMO, but you can get away with a good but noticeable repair per Randy's instructions. Either way will save the tank, it's just a matter of how much work are you willing to do, and how experienced with acrylic working are you... There is always the option of taking it to the local acrylic shop and having them make the repair for you

[VWD]

That is another good option, taking it to a acrylic shop and have them do it. But from what it sounds you have worked with it before.
