Resealing a tank?

[FishyReef]

Anyone ever successfully done this before? How hard is it? As I'm getting closer to getting the hex wet I'm starting to get really nervous about its integrity. I leak tested it on my deck for a few hours and it held water, but this thing is old and the guy who had it before me found it in a second hand store for $10 and then just glopped silicone all over the outside of it on the top of bottom and a few of the sides. I was going to hide the silicone mess with a canopy and turn it so that the clean sides faced out, but maybe I should just reseal it instead....

I would try to reseal the tank before you put anything into it because trying to seal a leak in a tank that has stuff in it is kinda hard. I would take a razor blade and scrape off some of the sealent and then start new just to make sure. Also I would wait 48hrs before you leak test it again after you reseal, you want it to cure fully before water hits it. I would use a clear sealent as well so if you have to use alot it is easyer to hide.

It is actually extremely easy, I redid all the silicone in my 75 gallon that has been running for about a year and a half now. I just put masking tape nice and straight around a year and half now.

Here's my build thread, and I show where I redid the silicone in the first post.
