My 75 gallon acrylic sump has started leaking at a seam!!! Please help

[SalteeDogg]

My sump has inherited a slow leak in one of the seams. Its not much, but it is leaking for sure and was wondering how I fix this since silicone cannot be used. I know they use a chemical bond or something on acrylic, so am wondering what I need to do to fix this. Any help would be appreciated.

Try superglue!

If you go through your yellow pages looking for Plastic Suppliers, you cant contact them to get the welding solvent.

Try superglue!

Does this work in a wet environment or in water?

It does. Try using the superglue gel.

Do not use super glue on acrylic. Take some acetone and clean the area. This will help clean the area. Then you will need wedlon 16 and a syringe. Slowly fill the area with the weldon and let it sit for 24 hours before adding water.
You should really empty the tank and let it sit dry for a few weeks first because the acrylic absorbs water, and needs time to go back to it's original size.

I actually found some weld-on 16 on amazon. Will probably just order some and see how it works.
