Just a little update. Had to buy a new furnace and dishwasher so set back a little. Ive got 150# of dry rock ready to be assembled. Stand is complete, just need to work on canopy. If my calculations are correct I think I have 230# of rock for this thing. Www.MarcoRocks.com is awesome. Great columns and flat rock pieces. Will updat with pics soon once I get my scape built outside the tank!
