I have been going through classifieds and have found a 7ft tank with sump and stand thats a year old for £600!!!
Great sounding deal!!!
Only issue with it is that its only 24" wide.... so if I do go for it, my knifefish wont be with me for very long (as he gets that long)
I think that perhaps the idea of getting a 2nd hand tank is best as the glass here is just crazy. And I have never even built a small tank, never mind a 180 gallon monster.
I do have some time with this as the fish are still manageable in my overfiltered 50gallon.... I still have to renovate the basement and im doing this myself on the weekends!
I have to tank the room for damp, put up plasterboard panelling on the walls, level the floor, put in tongued wooden flooring and a new ceiling!!!
If I go for that 2nd hand tank, its gonna sit in the upstairs lounge empty (wooden floor wont take it full) till I have completed my DIY.
When its done its gonna look great though...gonna post loads of pics
