I wouldn't do this on a display tank but if its your sump or refugium then just get some weld-on #4. I just got done building my refugium out of acrylic and its easy as pie to use.

The IPS stuff works great but just so you know - True acrylic cement is "methylene chloride" and is a carcinogen. It is best applied by syringe with a long needle to facilitate corner adhering, etc. If you are only dealing with a crack then you will want to get a thin liquid type weldon to seep into the crack.

how long does it take to dry,im assuming it its fish/reef safe?but where can i find the product?:thinking:

You can get it at the hardware store.
It is a nasty chemical that should be fully cured before you refill the tank if there's any chance of it seeping inside. Check the package directions.
