Well I have not done to much with the tank. I have been trying to sell as many frags from my 75 as I can. I have my rock work done. And will start the RO unit tomorrow or the next day. And for my canopy the guy that help me move the 75 and 180 is going to teach/help me build it. We plan on starting that next weekend. Here are some pix of the rock work. Not the best pix but you get the idea. And this is about 200 lbs of all lace rock.
