frag tank

[Aquattro]

Don't know. Last year, sure, but there have been reports of GE changing the formula. I used it recently on my sump, no issues, but others have reported lots of problems. Best to find some GE 1200.

don't use it-go to cascade and get aquarium silicone or go to your local glass company and get them to order it for you.it's about $12 for a tube of nuflex 333 aquarium sealant
