Resealing tank

[Tim Marvin]

I would not do it. If you do decide to reseal the tank, you should really redo all of the seals. This means scraping off the old silicone from all of the joints and applying all new silicone. You will get mixed results if you try to apply new silicone over old silicone. It is not recommended! I have seen it done and sometimes it will hold, but a lot of times it doesn't. Also, you will get a different coloration between the two and the joint will be very noticable. This may or may not be a concern for you.

I'd have to second this advice.

hey doug, i am going to have to reseal my tank. what did you used to scrape the old silicone? Did it seal well?

[dwdenny]

Thanks pacman it has been hold with no leaks for about 1.5 hours now.

Tim I did remove all the seals from the tank. I seems to be holding really well so far. No bubbles in the seals or anything.

Jerry I used razor blades and a scraper that holds them to get most of the silicone off then used acetone and rubbing alcohol to really clean the glass before resealing. If you have any question let me know.

[gjuarez]

cool, thanks doug. I will try to reseal tomorrow and I will tell u how it goes

[Tim Marvin]

dwdenny, good move. Most of the big tank makers will strip the tank back down to bare pieces of glass and just re-do the whole thing. I'll bet you are not going to have any problems for years to come! Great job.

The only thing that I left on was the bottom trim piece and resealed everything. I just drained it and had zero leaks. It sat with full water for 4 hours total this morning so I should be fine.
