Silicone.

The GE stuff would have probably worked fine. I just wouldnt rely on it entirely if I was custom building a large tank and the silicone was the only thing keeping it together.
 
ahh ok..gotchya:)

one is a 70 gal, the other is a 30 gal. Not too big I think!

both still had silicone holding the tank together between all the joints.....just needed a good reseal along all the seams :)
 
I thought that the tube had to say "food safe" to qualify. Slipknottin, are you saying that as long as the tube says "100% silicone" and does not have antibacterial stuff (wouldn't that make it less than 100% silicone??) it should be aquarium safe?

Can you name a brand found in the US that is one of these superior European types?
 
100% silicone is 'food safe' but likely arent rated as such as who uses silicone in the food industry?

There are no brands that are sold here that are European, custom tank manufacturers order the silicone from europe.
 
I have a 240G no-trim tank that is completely held together with GE Silicone II, has been running for months and has no leakage whatsoever. The only disclaimer for GE Silicone II that I can think of is that you need to let it sit for 10 days before subjecting the seal to water to let the stuff cure correctly.
 
Tim: please tell us that you only meant no corner supports. I cannot imagine a 240g without top and bottom bracing.

Slip: A plumber friend installs a lot of stuff in industrial/commercial kitchens and I think he uses 'food safe' silicone. I have seen the label before. Sinks, backsplashes, etc.

Oh no, sorry to give that impression. There are actually 6 support slats: 4-10"x23 1/2"x3/8" and 2-4"x23 1/2"x3/8". The slats on the top of the tank are supported by 1/4"x1/2"x12" glass strips, and everything is held together by GE Silicone II.

And no, Slip, there isn't any plastic involved in this tank.
