re-sealing your tank

[ndtyank49]

so i got a tank from a friend, sealed it, and it was good for 2 months but then started leaking. I know where it is leaking from. Should i just take the silicone and just seal over the old glue, or shud i take the old stuff off first and real seal?

what is chemically different about silicone that will kill the fish and will be safe?

Ok you have to remove the old silicone with a razor blade make sure you get it all new silicone won't bond to old.

The silicone that is safe has no anti mold or mildew agents in it. The stuff that's not safe with have it in it.

So look for a brand with NO anti mold or mildew

I have resealed everyone of my 15 tanks its not that hard
