So putting a 100G blowup pool in an un-insulated crawlspace turned out to not be the best idea for the coldest winter since 2008! Just took too many pumps, lights and of course heaters to keep it going and the evaporation was enormous. Just too much surface area. Other than that it worked great...
I set out to build a 40G frag tank for all of the remaining corals and some key live-rocks. I thought 1/2" glass would look cool, and it does! Total overkill on a 12" tall frag tank but it means I could try pull off some minimalist silicon techniques which turned out looking really cool.
The remaining rocks got bleached and assembled into rather elaborate and vertically unchallenged rockscaping. I'm still moving things around but have managed to create a couple of new and interesting areas with those and a new box of Marco rocks.
As of last week all the rocks, surviving inverts and corals (loosely dropped in) and fish are back in the same tank... all reunited and doing great. It's a bit of a blow being set back to the new-tank-syndrome stage after being so close to the 1 year mark but think it's for the best. White rocks and all ;p I have the sneaking suspicion there might still be some parasites left in the tank but after observing all the fish for 4 weeks after the 7 weeks in Chloroquinne could not draw any conclusions strong enough to warrant putting my livestock through more treatments.
The Kole tang got two spots, the day after I stopped treatment, on it's pectoral fin that didn't fall off or multiply in over a month and no one else as much as flinched / flashed / pooped funny or shook their heads at me.
In the meantime I've been making some progress in the fish-room. Plumbed in a 55G barrel to serve as a water-change zone so I don't have to turn the pumps off or drain the sump during water-changes. I simply isolate the barrel with ball valves, drain it and refill with premixed water. Also, I'm working on a remote DSB today to try and battle nitrates and algae in the year to come. I've always had great success with a DSB but the flow in my sump was way too high to make it work... ended up with fine sugar-sized aragonite sand washed into the display tank last time I tried.
Also, the Barracuda pump got some silicone carbide seals (U.S. Seal PS-1905), they REALLY work! If anyone out there is running a reeflo pump with a leaky seal this is a no-brainer and worth every cent. Every other factory seal kit I've used ended up leaking after a while on both this and the previous hammerhead gold pumps.
Overall I'm in good spirits about the tank and looking forward to the year ahead to watch it grow back to where it was. After 18 months of starting this build I get to glue my frags into place, TODAY!
