So I have a 300 gallon paludarium of Madagascar and I just finished it and it came out really nice and this morning I was going to post pics of it until i noticed a hairline crak going from one corner to another on the base(its elevated) dripping water. Im asking what the best solution is. I have drained the tank and moved the fish and thats taken care of but should I remove the bottom pane and have it professionally fixed or apply a regiment of glass sealant and silicone and go that route? Thanks, Jonathan
