That's the old 135 in the photo; the hole in the wall is just big enough to slide the 260 in; the 260 is in the hole and being filled with water as we speak; I followed Roy's advice and used the Turface as a substrate and also threw in some sand for my future stingrays; That Nymphoide Taiwan (sp?) that Santa brought me is growing great (Thanks Roy!); I've got several new leaves and roots; Once I've proven that everything is working good I will frame in an enclosure around the back so I can insulate it; I will put hinges on one of the back walls so I can swing it out for filter maintenance; This is the second tank I've built into a wall; This one sticks into the office about 24" whereas the last one I did we built it flush with the wall and framed it like a picture which turned out great; But this one will be easier to service from the front; Well all for now I need to wire a separate circuit just for the aquarium so I can tie into our generator circuit for power outage contingencies; Have a great weekend, Jeff. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
