Repairing galvanized stock tank, lefd05, anyone?

marti8aApril 22, 2007

I have an oval galvanized stock tank that dh stored pool chemicals in one winter. Now it has a big rusty ring in the bottom. I filled it this spring & put lilies in it, but the water is rust colored. I need to fix it before the bottom rusts out. Any suggestions?

I was going to get some rustoleum spray paint & dh told me that wouldn't work.

You will need to sand it down and clean it real good. You can either paint it with a vinyl paint or have it sprayed with spray on bed liner or pond liner. Wal-Mart here has a roll-on bed liner. It's $100.00/gallon. I plan to use it on my 6'diameter galvanised stock tank.

Happy ponding,
Scott

marti8a, about 4 or 5 years ago, my 10 ft wide stock tank started leaking. I drained it and found out that there were about a dozen small holes in the bottom.

So I let it dry well and then put some small round sheet metal pieces (used for roofing) over the holes. First I put some of the tar down and then the metal pieces on it. Then I tared over top of that. I put tar all over the bottom since it was rusted fairly well.

The tar that I used was Submarine Cooler Coating for evaporative coolers that I bought at Walmart, for $4 per quart.

It hasn't leaked since I did this. One concern I had was if it would hurt the fish or the waterlilies? It didn't seem to affect either of them.

So you might consider using that tar to cover the rust? It works best if you use a paint brush and wait for warm weather so it will go on smoothly.

Also wear some old clothes that you can throw away in case you get any on you.

cfsam, did you put fish in it after that?

I do remember those evaporative coolers, but bet that tar is hard to find here where it is so humid.

marti8a, I let the tar set for 3 days then I filled the stock tank. Then I treated the water for chlorine.

Since I wasn't sure if it was safe, I bought some feeder goldfish and put them in there.

They did fine so after a couple of weeks, I put some of my regular fish in there and added the waterlilies.

You are right. That tar might be hard to find in humid areas.

My DH takes a wire brush and cleans the rust out of the tanks. He solders any pin holes then he washes the tank off and lets it dry well. If he thinks it needs it he runs a thick bead of clear silicone around the bottom inside seam and lets it dry for at least 2 or 3 days. DH buys spray cans of automotive undercoating at the parts store. He sprays the outside bottom of the tank and sometimes if the tank is really bad, we spray the inside bottom with it as well. If the tank isn't too bad I've used Krylon spray primer on the inside of the tanks to help protect from rust.
I've kept water lilies and goldfish in old tanks done this way and had no problems. So far, a couple of my tanks are going on their 3rd year and still holding.

marti8a, one of my large stock tanks is about 20 years old and is still okay, except for some tar patches. The other large one is about 14 years old. Then I have a newer one that is only about 4 years old.

Out on ranches, these stock tanks last for 50 years or more. Of course they are sitting on the ground instead of being buried which is probably better for the tank.

It sounds like your DH and you have a good system going for repair work.

I wanted another stock tank to put lilies in with no pump or filtration. Hubby had one at the farm that was beyond repair. The bottom was loose about 1/4 way around and it had some holes in the bottom about as big as a pop can. I lined it with old carpet and used a $15 kiddie pool for a liner. So far it is doing great. I'm not even loosing any water to evaporation. I didn't want to use a kiddie pool alone because there are dogs that run free in our neighborhood and I was afraid they would destroy it. The liner fit my 8' tank perfectly, but just not all the way to the top.

I think it turned out ok. Dh used an epoxy for metals. The only complaint I have is that it is white, but I'm sure that will be green soon enough. Haven't put any fish in it yet; that will be the test.

You could have gone to a paint store and got some pigment.

Happy ponding,
