astroboy May 12, 2018 Share May 12, 2018 A few months ago when I was scrapping algae off my 90 gallon with a razor blade I made a deep cut in the sealant on one side, near the bottom. Nothing bad happened so I figured no harm done. Last week the tank started leaking; fortunately I was able to save everything, I have a 75 gallon tank for mixing salt water. I'm thinking about scraping off all the old sealant and resealing the tank. According to you tube, this can be done successfully. Does anyone have any thoughts on this, in particular, what sort of sealant to use? Thanks, Mark Link to comment Share on other sites More sharing options...

gmerek2 May 12, 2018 Share May 12, 2018 It’s not worth the risk. just buy a new one that will last forever and sell old to a reptile keeper Link to comment Share on other sites More sharing options...
