This reminds me of how my in wall 75 gallon got installed.
On Christmas morning, the kids got a wii u. We took it to the basement to hook up to our 14 year old rear projection HDTV. Well, once the tv was turned on, the picture was all messed up. No amount picture timing or TV set resetting was fixing it.
The wife and I decided then that when my work bonus check came in, we would get a new led
tv. But the condition was that she gets a good entertainment center for it with lots of shelves for books and the kids games. Not a problem. The bonus should cover both.
Well when looking at the wall this entertainment center would go against, we realized that new carpet was needed since our basement wasn't completely finished. Everything was done except for carpet and we were using remnant carpet from a neighbor. So on top of a new tv, a new entertainment center, we were getting anew carpet.
An estimator for the carpet came to give us a quote and he said they can move all furniture except for my 55 gallon tank (which was on a temporary stand and location). I decided that I was moving my tank just once.
That's how the 75 gallon in wall tank came to be. I cut a hole in the wall for a 55 but then I decided I wanted to go slightly larger.
So my in wall tank with a diy sump was the result of a broken tv.
Sorry for the long post and hijack.
