Well today was another good day for work on the tank....:splitspin My day started with a delivery from reefcleaners. I have never seen so many snails in one bag lol...
Next item on todays agenda was to start building a canopy. Now this might seem like an easy task but when I started thinking everything out...my head started to spin...:splitspin In my mind I wanted a clean, functional, and attractive build. I also have a couple of huge issues.
1) How was I going to get this 150lb 10ft canopy off once assembled ?
2) How was I going to controll all the heat in the canopy ?
3) The canopy was in an area where I couldnt lift it straight up(i would hit various things)
4) Moisture resistant
5) Hold all the lights & equipment and not look to bulky
Well the first step was to use a commercial grade Moisture resistant plywood in 5/8 as a frame. The face will be covered with a laminent and the inside will be painted with a product called Brite Coat. This is a highly reflective white paint. Then this will be sealed with 4 coats of poly. The next area to build would be a light rail. This will be mabe out of 4-5' aluminum L beams with one center brace for help with the weight. Using this aluminum L beam will allow me to move my Mh fixtures left or right enabling me any configuration I may need. In addition, they will not rust and will not be affected by the heat given off by the halides. Directly under the halides on the bottom side of the aluminum L beam the VHO's will be rivited to them spanning 10' in front and 10' in the rear. In between each metal halide lamp will be one moonlight LED connected to a lunar controller. Bolth the Lunar controller and Vho ballast will be attached on top of the canopy in moisture resistant box. There will be 2 4" variable speed fans one pushing(left side) and one pulling(right side) that exhausts out to an HRV. The front of the canopy will have three openings 26" X 14" to feed and do minor cleaning.
The next part is the pain in the A-- part. I also realized that I would need to get into the tank and have more accessability so this is where it got fun. My carpenter came up with a rail and winch system. You are probably scratching your head right now and I was too at first. Basically by using a winch and heavy duty rail system it enables me to lift the canopy 6 inches off the tank and slide the canopy over roughly a foot and a half and then have the ability to crank up the whole canopy three feet above the tank....:splitspin. Now this SHOULD work...key word being should...we will find out very soon. Or you may see a grown man cry. Here are some pics of the progress...
Testing to see if the frame fit correctly....
Later that evening.....
