    All the following up for grabs by weekend before they go into recycle bin:

    1) Jerry can - microscopic leak at bottom. 

    2) Tunze CR casing - both ends removable... with strong magnets... Can be converted into frag rack+isolation box  with some imagination.

    3) 6 4ft 54w ATI T5 tubes - one year old but still good for FOWLR.

    Am not sure how much free space there is above the tank... for days when u need to stick your arm into water.

    Otherwise it looks like a fantastic system... removes much of the back-breaking chores associated with this hobby.

    Since water change is one of the most important husbandry of reef tank maintenance , one consideration that we had was to make the water change process extremely hassle free.

    as the house is rebuilt, we were able to install a drainage system right under the tank cabinet. 2317FB68-EFB4-44C9-9A2A-C8FF2C345DD0.thumb.jpeg.4f79541c7e6e92df59d355041007d108.jpegThis drainage pipe is estimated at a height to drain about 15-20% of the tank volume, an optimum amount for water change. It is controlled by a ball valve, once open, the water will flow down to the drainage as shown in e picture below.4F1D46FF-FF6F-4B64-B8EF-CD0A8DA71663.thumb.jpeg.5d8ce9aa3db4841c4372c5706d9e5f82.jpegthe RODI waste water tube is also connected to the drainage pipe! And yes the RODI is installed within the cabinet!

    so water change is just, drain the water with the drainage pipe, pour the salt into mixer tank, switch the valves to pump the water up to display tank. There you go, a water change process without pails!

    haha, love to hear your comments on this!

    Won't there be days when u need to vacuum sand, dust rocks and scrape algae? Top cover impedes these manoeuvres, no?
