Okay, I resealed my 210 and everything went pretty well. The silicone dried to fast for me to peal up my masking tape, but I'm not to worried about that though. The problem I have is that after I got done I found a few areas that had air pockets. I guess I have two separate questions about this. A couple of the air pockets were not very big and there seems to be a fair amount of silicone covering them. Do you think it would be safe to leave them? The second question. I felt that several of the air pockets were to big, so I cut the silicone out and have planned on resealing those sections. Will it be okay to "patch" these places? Meaning there would be fresh silicone butting up to newly cut and cured silicone. I'm thinking that if I make sure to clean the newly cured silicone with acetone, and maybe overlap the fresh silicone over the older silicone it would work. As a clarification to those going to say that new silicone won't stick to old silicone this tank has all new silicone and has not had water in it since it was resealed.

I had a similar issue when resealing a 25gal tank. The air pocket was on the bottom seam so I cut out the section and resealed it. I made sure to overlap the previous silicone a bit to try to ensure that it was sealed (not sure if it helped or not). The sealing took and now my fish tank is leak free.
Now if your air pocket is on a vertical seam that will be seen I would also start from scratch.

I think it depends on how big the bubble is and how much you're going to be vexed by it. If your the type that when you look at the tank and all you'll see is the air bubble, redo it. If its big enough that you're worried about structural integrity, redo it.
If its just a couple smallish bubbles, I'd call it done, fill it and be happy

Well, I've been busy and hadn't had the time to work on it. I just fixed the bad sections. I had already cut out some of the bad sections, so last night I finished cleaning them up and taping them off. This morning I put down the silicone and am very pleased with how much better it looks. The only thing I am worried about now is if the fixed sections will leak where the new silicone meets newish silicone. I did overlap some so hopefully that will help.
Just wanted to post a followup. It's been a while since i started this project but it's finally coming around. Anyway, about a month ago i got the aquarium in my garage and filled it. I let it set for a week and no leaks. I have since brought it in my house and had it filled with water for about 2-3 weeks and everything is still good. In hindsight i probably should have just left well enough alone...
