Title: 150 gallon reseal
Post by: Marty on July 02, 2013, 05:10:44 PM
I picked up a 150 gallon that ended up being a leaker.  I finally had some time this weekend, so I scraped off all the old silicone and resealed it.  This is the largest tank I've done so far, but I actually thought it was easier because I had plenty of room to work inside the tank.  I probably should've taken more pics, but here's a couple with it holding water (six hours since I filled it).

I wouldn't say the silicone looks professional grade, but it doesn't look horrible either.  Next time, I might actually break down and buy one of those spatula type things they sell on tv to make the bead look better.

I filled it to the top.  I have it sitting on some 2 x 4's to even out the pressure instead of putting it directly on concrete.  I filled it in the garage to keep from flooding the house in the event I didn't do a good enough job with the reseal.

It's really not that hard, you just have to make sure you get ALL of the old silicone off the glass.  It's more of an attention to detail/tedious job.  I went through around a dozen razor blades on this one.

Typically you're going to know if it's going to leak within a few minutes.  I'll leave this one filled for a week just because it's so large and it's not in the way right now anyhow.  I've done this to a couple of dozen tanks and only had one leak (because I didn't get all of the old silicone out of a corner).

After doing a 75 gallon recently I came to the same conclusion about getting something to help spread the silicone.  I have heard people talk of cutting up an old credit card to do the corners.  I might give that a shot next time.  I have also heard an old spoon works good too, but I think that would be less uniform.

rubber glove and a little rubbing alcohol on the tip of your finger and it spreads nice

As I recall, I have used vinegar on the end of my finger too.  (that was about a million years ago)

Wal-Mart sells caulk tools two kinds.  I bought both but i like the one with the removal tool attached to it.  I have used it on a 30, 10 and my 150 works great.  The removal tool is useless with silicone.  I think it was around five bucks in the paint department

You can probably get the same thing at any hardware store. 

Forget Walmart.

Isnt it better to let it sit 24-48 hrs before adding water?

more like 48 hours

I waited about a day before I filled it with water to allow the silicone to cure.  I would wait longer if the weather was cooler.

What I meant when I said that you would know if the tank was going to pretty quickly was after it was filled with water.  A tank this large would exert a great deal of pressure on the seams, so if there wasn't good adhesion to the glass, the water would likely push through rather quickly.

I was told by a old aquarium builder at one point on big tanks they would clean the seams up really good then put new silicone in and then cover it in plastic and fill the tank. The pressure would cause the silicone to be forced into where the water was leaking out at... Ive never tried it, Maybe one day I will.

I've never heard of that before.

I have seen smaller tanks that had leaks plugged by smearing a big glop of silicone where the leak was (this was while the tank still had water, but no fish in it).  This was about a 20 gallon tank, and it did work.  I'd never try that with a larger tank.

I think I'd rather just take the time to redo the whole thing with new silicone rather than take a chance on a shortcut.
