You're always safe with sealant actually made for aquariums. Aside from that, you can use any 100% pure silicone sealant. G&E Window & Door Clear Silicone I sealant works. Don't use the Silicone II version, as that has mold inhibitors and other nasty stuff that might harm your critters.

SO I'm not sure if this will do or if I should start a thread but here's my question along silicone lines:

I have a 75 gallon that's probably 15 years old. What's happening is that there's algae growing under the silicone in the corners. There's never algae in the tank between me using a sponge and the pleco, but it's in the corners, just beginning to separate the sealant from the glass. I'm afraid that it will cause a leak eventually.

Anyone ever experience this? I'm not sure what to do about it. I could cut a line because it hasn't made the corner yet and then add more silicone, but silicone won't stick to itself so I'm not sure if that'll help. I don't really trust myself to rebuild the whole tank, but I'm not sure I want to spend whatever a 75 gallon costs.

Suggestions?

That's something to start a new thread about. Are you sure it's not mold?
