btb72 - It'll hold about 450 gallons.
joeychitwood - Thanks, pics to follow. I first have to buy a bunch of useless stuff before I can get the tank wet. You know, like a lawn, curtains, furniture, and other things that are just a waste of money.
reefscape15 - I live in Texas, and beneath the slab is limestone, so there is no basement. The tank is on the 1st floor of the house. The PVC is the location of the floor drain. The room is gently sloped to that drain, and the drain leads out to the street beneath the slab. So if there is a leak, or even if I want to just mop out the room, all of the drainage will be directed to the outside. All of the tank's equipment, including water storage, will occur in that tank room, so there is no separate room. And I agree, I didn't think mine was a corner tank worthy of this thread, but I was asked to contribute and so I did. And since I'm 3/3 with regards to being accepted, then I'm happy to be this thread's newest member :thumbsup: . If nothing more, I'm looking forward to learning from all of you regarding the challenges of maintaining a "true" corner tank.
