We don't recommend any of our products for underwater submersion, but some aquarium manufacturers do choose to use our products on glass to glass aquariums. The products they use most often are RTV108 or IS808. These are industrial grade products. Our consumer grade (this means they would be found at Home Depot or a local hardware store) offset to these industrial grade products is GE012A (Window and Door Silicone I).

So I would say it is as safe as it gets without specifically stating so.

If you must have one that says safe for aquariums get the all glass brand or Loctite has one Called Extreme repair that states it is safe for aquariums up to 30 gallons and 18 inches of water height.

Ive used GE RTV108 from 2.5 gallons all the way up to 230 gallon tanks for reseals, rebuilds, and glass replacements.

My last rebuild, was a 55 gallon. Had to replace both the sides on a 55 due to a cleaning goofup. I took the entire thing apart, cleaned off all the old silicone, ordered 2 new side panels and put it all back together. That was over a year ago. That tank still holds water with zero leaks.

Good Luck!

I resealed a 55 with GE I, no problems.
Part of the reason they won't say directly that you can use it for aquariums, is that if anything goes wrong, they don't want to be held at fault. Also by doing so, you can sell the "true" aquarium sealer for much more.
