I recently used GEI 100% silicone to glue in a new front and side panels on a 170 gallon aquarium. When I filled it up I was watching the seams where I glued the glass togther, I saw the silicone start to seperate from the glass. Now im very paranoid about having this tank in my house filled with 1400 pounds of water! so im going to cut the new panels out and redo the whole prosess again! This time Im going to go all the way and buy the best and strongest glue/silicone I can use! My question is, what kind of glue/silicone should I use? I have heard recently that RTV is stronger then regular silicone. Is this true?
Thanks,
Nick
 
Do you have trim on this tank. I honestly wouldn't use GE1 without a trim. Tanks with no trim scare me.
 
The tank will have a frame but it dosent right now. It dose have 2 front to back braces that are 8" wide. The seperation in the silicone was more twords the bottom portion of the joint. I let it sit for a week and one day. I applyed the silicone last week on saturday...
 
RTV is the stongest stuff I hear, i used it to seal my 130g, still havent test filled it as Im away for a while.

Make sure you get a frame on that tank... or angle iron or something. the frame on my tank is crappy so i put a couple clamps to hold the tank together :P
