Resealing and Curing in heat?

[PaulieReef]

Getting a used tank tomorrow (8 years used), and the silicone seals are a little rough, peeling back, attacked by fish etc.

I wanted to know if it was safe to reseal in my garage, where the air can range from 90-105 degrees and then post cure, put it in my house, where it averages 68-75 degrees.

The tank is 240g , 8x2x2.

Some pictures of the seal.

was thinking of doing something like this.

Paulie, to be honest the seal just "looks messed up" but is fine as far as sealing.
If it would make you feel better just cut it straight with a blade & ruler or straight edge as far out as possible. Otherwise your plan should work but may not look that good either that far into the glass.

Appreciate it. I guess I am just scared that if I run this tank for 4-5 years, it will start to leak and I will have to drain it, repair and what not. But if everyone is saying its fine, I am sure it is!

Yeah, it's fine, I wouldn't have a problem using it as is. However, if you want to redo it to slow down the algae working it's way into the joint or for just aesthetic reasons your plan is fine and doing it outside isn't a problem. For a neat looking reseal after removing the old silicone and cleaning the surfaces well with alcohol use painters tape and tape off teh joints. After puting down a bead of silicone use a plastic spoon to press it into the joint and feather it onto the tape. if needed use a exacto knife or scapel to cut teh silicone along the edge of the tape for a clean straight line.
