I have a 120 gallon tank I got for $80, and I'm resealing it. I didn't do a leak test, but the silicone looked like it'd been eaten away at the edges, so I decided I'd rather deal with it now while there are no inhabitants for the tank. I've pretty much removed all the old silicone.

My main problem is getting the last bits of the really thick silicone in the corners. It's really tenacious and since it's in the corner, I'm having a really difficult time getting it. Any tips? I've been using a sharpened chisel, razor, and denatured alcohol.

Also, I know you're not supposed to remove the silicone in between the panels. In places where it looks as though I've gotten everything, there will be a very thin strand of silicone right in where the two panels meet, that sticks out in places, and it looks like I should take it out, but I'm not sure if this counts as the stuff I'm not supposed to remove, and I'm paranoid I'm going to ruin the tank if I take it out. But it also looks like it would get in the way of the new silicone.

The silicone I bought to use is GE 1 clear, but I just realized tonight it say Kitchen/Bath/Plumbing (and I know it's supposed the be the door and window kind). But it says nothing about any mold inhibitors being added. Do I need to return it?

Last question..the trim at one corner of the bottom of the tank is cracked..not completely through the entire piece, but mostly. I'll post pictures of it. Should I worry?

I wouldn't worry about the trim as long as the glass is adhered to it well. Buy some super glue - the two part stuff works well and will chemically bond the plastic together. I think it even comes in black.

As far as the old silicone, remove as much as possible and remember that new silicone won't stick to dry silicone so just make sure it touches both pieces of glass always, even if it covers remnants of old silicone.

Aquarium safe silicone is available. Dont use anything designed for kitchen or bathrooms as much of it contains mildew inhhibitors that are toxic to fish.
