My 20 gallon reef was officially set up May 26th 2016; however some of the livestock and live rock were taken from my 5.5 gallon reef to start and I had pre-cycled the rest of the live rock. The tank has a custom built wooden canopy and two built in refugiums. I’ve learned from my previous reef tanks and avoided making the same mistakes.
Similar to my 5.5 gallon reef, the wooden top is divided to allow for an alternating light cycle over the built in refugium. This top does a better job of blocking the light from the refugium at night though, so there is little to no light that shows in the main part of the tank at night. For the refugium light, I just used a screw in 6500k fluorescent bulb that I got at a hardware store. There is also a small fan in the canopy because something I learned from the 5.5 gallon tank is that water condensation builds up very quickly without a fan in the wooden canopy. I ended up painting the inside of the canopy white after the picture to the right was taken.
The two built-in refugiums are divided into two sections, a part for the pumps and heaters, and the other part has chaeto, live rock, sand, and miracle mud. I ended up having one refugium for cheato and the other I use for live rock. I do regret not making them more accessible, because in order to access them I need to remove the whole canopy to do so.
I also use a smart plug for my pumps since it’s easier to turn them off during feedings that way. Also, I programmed the plug to turn on every hour, that way if I forget to turn the pumps back on after feeding, they will come on automatically.
