I moved into a smaller house so had to sell some tanks down to 1, 200 gallon,,no room on the 1 still floor was thinking about a tank in the basement,,the place I bought had the kitchen added to the back of the house and is 10' x20 ,,there not basement under it its broken into 2 ,10' x 10' foot rooms that looks to have walls that go down not sure how far its has a 3 foot crawl space ,with a 3 x 3 window,going into the basement from the inside,I thought about digging it out 3 or 4 deeper cutting the hole for the front glass bigger ,,it would be a big project,,am I a little crazy or what,,,and does anyone know what type of stuff I would have to use to seel the glass to the back side of the wall I figure when full all the presure the glass will stay,,thanks wayne
