Does anybody have any tips abotu sealing a leak in an acrylic tank? cobalt sold me his 90 rr and when i filled it with water it started leaking. I think he said Andy(myreef) sealed the leak once already but i think that its leaking agian. I bought some acrylic glue from the fish store and more to seal the tank. I really like this tank but i cant keep it if its too hard to repair. Let me know if anyone has any tips.. thanks!

Acrylic sealent is mostly methylene chloride and it chemically bonds the acrylic. The IPS Weld-On products are great. If you want a quick bond use the lower numbers like Weld-on 2 or 3. This will set in about 30 seconds, but isn't really strong for another 24 hours. You can add acrylic shavings to the crack as well if you use Weld-on 2 or 3 and it will dissolve into the crack. The higher numbers like Weld-on 16 are thicker and require several minutes to set up and usually require you to use a clamp to hold the pieces together. But you can use the thicker paste to fill cracks in the acrylic, but it is somewhat messy. I would use the lower numbers, without shavings to see if that works. If not, switch to the 16 and fill the crack.
