This 125 is going to give me a heart attack. It's been one thing after another, but it was a steal, so I can't complain - unless it goes bust!
After I committed to buying it, the seller, a coworker, told me the rim was cracked but the tank wasn't bowing. He said he would clamp and epoxy the crack before I picked it up. He did, but used Gorilla glue and it didn't hold during the move. I used a two part epoxy for plastic while the tank was empty. Today I noticed it cracked again sometime after I filled it. I took detailed measurements to monitor it - hopefully it won't spread before I get the two steel bars made. If it does I'll drain 1/2 the tank to take the pressure off. I was going to get two stainless steel bars made that would sit over the plastic support bars on the rim, but in my eagerness to set the tank up I forgot all about it. Ones that are bent and hang over the edges, acting like a support/clamp/brace combo. Now it's on top of my list! I may drain 5" or 6" anyhow, do you think it would help take some of the pressure off?
I called the guy I bought the tank from, and he said the rim had been cracked like that for a year and the tank was full the whole time, so I'm hoping it's stable - I know the tank was full because we helped empty it when I picked it up. The crack has a max gap of 2/8" and is 5" long. The tank IS bowing at the top, and it had to have been when he had it, he must not have measured it - it's not visible to the eye. (the crack isn't any larger than the original, in fact it's a bit shorter) The glass bows out at the very top 2/8" of an inch at it's peak. I'm keeping a close eye on it!
Some bad pics...the bottom one looks bowed on the perimeters because of the zoom of the lens - you can't see anything in person.
