6' Frag Tank Build

[Grayout]

One of the Hagan tanks was to be the display/growout area with the other one a sump divided by glass baffles. A Gyre XF150 would be mounted on the left side of the display pushing water down the length of the tank to a spillover. The spillover water flows through a bean animal overflow.


I really like the design of this overflow and the triple redundant features which pretty much rule out a clogged drain. Since I would be leaving this system for a couple weeks at a time it was important to have it almost fully automated. The next step was to start drilling the .5" glass to create the overflow and drain pipes to the sump.

I also had to fortify the existing metal work stand to cope with the heavy weight, so I built two frames that would be tied into the plywood top. After the sump's glass baffles were siliconed into place and drain holes drilled it was slipped within the wood frames on top of high density foam. The two frames allowed me to fit the sump in at an angle which would not have been possible if the stand was built as one piece.

After the drills were done the sump was slid into place. The chamber on the far right where the overflow water initially returns houses the skimmer, then a chamber for live rock, a chamber for a six inch DSB lagoon and then the return pump chamber with heaters and dual carbon/GFO reactor.

There were a few leaks from the bulkheads/PVC fittings during the freshwater test but nothing too serious. Sometimes when salt is added the leaks cure themselves. So, I transferred the contents from one of my smaller tanks to this one to start the biological process and reduce the cycle time.

Reef Dynamics calcium reactor installed and water change 60 gallon barrel fabricated. Just mix salt and let pump recirculate until ready and roll it to sump for a quick water change. Three Kessil A360W's installed on goose necks for maximum light spread over 72". Neptune Apex installed next to control everything.
