I always had a plan to build a fish tank in the wall on the main floor, but after seeing the project you undertook i might be changing my mind. in a little fish shop i was in back in Illinois the had a little 6x6x6 concrete block tank it sat on the floor of the store and was dark i guess that's why i never really paid it no attention. your tank it up and lighted very eye catching. thanks for sharing if at all possible would you give us an update on the performance of the tank and some pics
