now theres got to be a limit to where fish tanks go , but thats cool and it works for me ! i might of just seen a good place for some swimmers to go ,food for thought i'll have to draw up some plans for that one . still working in the tank in the minivan filled it 3/4 of the way up and it bowed out a little to much so i'm gonna brace it a little ,should be simple. i used 1/8 "plexiglass and that was a little to thin ! i will win this one , next is the heater ! oh yea how are you heating that toilet ? does it really have fish ? cam\nt see in picture , looks cool though !
