I’m trying to keep track of my progress and to hold myself accountable to work on this diligently. I have a 14 year old custom-made 90 gallon. It’s all star fire glass and I neglected and just let sit empty dry and dirty for all those years now, though silicone still feels very pliable nothing feels dried out or anything, but I’m thinking about putting more silicone over top of it just to be safe? Thoughts?
