Update: This weekend I got a lot down.
First I made a top flange for the refugium so it would not bow when it was filled with water.
I began building and almost completed the sump. I hopefully will complete this week. In the picture it is on its side
I also went to Lowes and picked up a bunch of plumbing supplies. Instead of using acrylic rods to make rock pillars. I found these mailbox reflectors that are made out of fiberglass and are even strong than acrylic rods.
Lastly I had and extra water faucet laying around and came up with a brilliant idea. I am going to drill a hole near the bottom of the sump and put a bulkhead and then attach this water faucet to the bulkhead. So on water changes all I have to do is hook up a hose and run outside.
