A couple of updates.
The kole tang has ich, though he appears to be the only one affected, and he's still swimming around and eating well. For now, I'm in vigilant watch mode and doing a number of water changes to make certain that parameters are great for recovery. If things make a turn, I'll set up a hospital tank and take more effort. The biggest issue is that he's currently in what I was planning for a hospital/qt tank, so logistics are a bit of an issue.
Second, I ran by my stand design by a few of the folks in the DIY forum for structural input, and there seems to be little issue. It's intended to be constructed from 2x8 cross members and 2x4/2x6 legs. Here's a couple quick sketches I made. It's very simple and straight-forward, I'm trying to leave enough space under the stand for the 60"+ sump I intend to build.
In air conditioning news, I came home with a portable LG unit, but apparently they do NOT have fans controlled by the thermostat. What's this matter? Well, that fan blows 250W when on, so that particular unit will go back to home depot. I've shopped a number of online companies asking if they do have units with fans controlled by the thermostat, but to no avail. The only other alternative (other than moving towards a mini-split) is to find a unit that does come back on after a power loss and use a plug-in thermostat. I'm concerned about doing this, but I'll have to figure something out and probably within the next few weeks.
Finally, I ordered 8 Cree LEDs, a meanwell driver, and some aluminum stock (from estoconnectors) to try out my plan for morning/evening supplementation. This is definitely an experiment, but I wanted to play around before committing to all the hardware. I'll take some pictures as I get it put together, but I've only ordered everything in the last day so it will be a while.
