That's it.
Barry completed replumbed the 230g tonight, installed the pump we had purchased secondhand, only to find the rear seal shot and water pouring out.
I know the person we bought it from was not aware of this as he never used it. I don't blame anyone, it's just enough.
The tank hasn't been that rewarding for some time now, one problem after another, and we are both exhausted, physically and monetarily.
I'll be taking some pictures and posting the whole system up for sale as soon as I can.
We will continue to reefkeep with the smaller tank.
