I need help with tank reseal questions
First I'm wondering if I need to reseal the tank at all. It is an older 75 gallon with 1/2 thick glass. The seams seem to be in good shape, but I noticed a few air bubbles in the silicone where it is spread thin on the glass. I also noticed some small cracking in the thin area at one lower side. other than that it looks good.
Should I reseal the tank?
If I should reseal it...
Can I just trim out and clean where the exposed silicone is located along the seams without taking the tank completely apart and removing the sealant within the seams between the glass?
If I reseal I plan to use RTV-108 silicone. How many caulk sized tubes would I need to reseal a 75 gallon tank?
