Some of the glass has hard water deposits and dried up grunge, I figured dropping the whole glass in vinegar for a few hours should have it all clean and shiny.

I was thinking today, maybe what I'll do is fill a rubbermaid tub with vinegar and water to soak and finish cleaning the pieces of glass.

I've read also using acetone ( nail polish remover ) works well to clean bonding surfaces.

Only a geuss, but I think they mean marine as in don't patch a hole in your boat with it. Ya, I figured that's what was meant, just found it interesting. Kinda sounds like 'Don't use it in water .... Ok use it in water'

I went back to Home Depot, and you are right, GE silicone 1 dosen't say 'not for aquarium use'. I picked up a couple of tubes and I think I'll use it for any non structural repairs. I have 2 tanks that I am replacing panes of glass (making 2 tanks out of 4 broken tanks). If I can find it, I'use the GE 1200 series silicone for them. If I can't find it, then I'll go with what I've got. Next is to find and assemble strong enough shelving to set all the tanks on and set up a sump for them. Blaine

Does Riverfront sell the GE 1200 series silicone ?

The question is.... What is a good, inexpensive aquarium sealer ? I have searched this and a couple of other forums, gone shopping in pet and hardware stores etc. The only answer I have come up with is that everyone has a different opinion. I have some used 15 and 20 gallon tanks that I would like to start using. The plan was to peel out the old silicone and reseal the tanks in the hope of preventing any leaks that could occur at the worst possible time. The cost of sealant made for aquarium use is almost as expensive as buying new tanks. I found, searching posts that some people are using GE silicone 1 to reseal tanks, others using similar products. On the tube for GE silicone 1, it states 'not recommended for use in aquariums'. Canadian Tire Mastercraft silicone says on one line 'Not suitable for marine use' then 2 lines down in bold print 'Excellent for use in aquariums'. :boxed: Anyone who has any advice on this subject would be greatly appreciated.
