That's too bad Mike and Terry. I'm glad to see the community and LFS are supporting you guys so well.
How can you tell it was a defect?
At this point I'm seriously considering installing a drip tray/drain pipe mechanism into the new 120's stand.
Lucas, After our first disaster, we brought in a structural engineer (he also has an aquarium) from Seattle to consult with us on reinforcing our floor and building the tank stand to ensure the tank was properly supported (and then some) and there would be no deflection issues.
When Perfecto built this tank, they broke the bottom pane while drilling closed loop holes and had to replace the glass. They also did a very poor job of sealing the center overflow box (the overflow box actually peeled away from the glass (completely on one side, partially on the other) two weeks after the tank was installed. The vertical silicone seams between the glass panes on this tank are 1/8" wide, except for the back lower left and the back upper right which are about 1/4" wide. The left pane tilts OUT at the top rear about 3/32" perhaps more (hard to get an exact measurement with the messy glob of silicone on the outside. The right pane at the top rear tilts IN the same amount as the left tilts OUT.
So we took a look at the vertical seams on the 200dd temporary tank. They are 1/16" and while the silicone is sloppy and the side panes appear to tilt in by 1/16" in the rear, at least they are mirroring each other.
We have always installed the thick black shower liner material under our stands. Funny thing, with both of our seal failures, the water didn't actually end up inside the stand, but made it's way onto our counter tops and into the floor in front of the stand and also onto the floor inside the side cabinets (where there is no liner - we're going to change that with the rebuild).
Wow guys! I just caught up and read what happened! I am soooo sorry. I had just joined r2r back when the first one broke. Thankfully you have a lot of good people helping out :D I would be there too if I lived closer :(
Thanks Jackie and yes, we are lucky to have great friends and local club members who have been real troopers to help us out. We can't thank them enough.
