I've come to the conclusion that I'm just too busy recently to do a coherent job on 4 tanks. I have enough time and energy for 1-2 and as a result, all 4 are in various states of neglect.
I have a 75 gallon RR complete system that I am considering getting rid of, with about 40-60 lbs of rock re-cycling in it due to near-total neglect. I have my old 45 gallon in a state of benign neglect, but a spike in salinity, fall in alk, and some urchins munching through their branches have annihilated my LPS corals. I have a 125 that is FOW/LR right now that I don't want to get rid of (~200+ lbs of rock & 6" sand bed), but one of the visitherm stealth heaters broke and the wet heating element popped out of the tank and landed on my timer/surge protector. If I hadn't been home and fairly near the tank to spot the fireworks as they happened, the resulting electrical bad thing might have burned down the house. (Casualties: 1 florescent light, 1 surge protecter w/built in dual timers, 1 heater. I also have to re-wire to create a new set of driploops, since I was using the surge protector placement to help handle that.) Lastly, I have a 29 gallon freshwater that is doing pretty much fine, because it has fish that are OK with neglect.
If, as I'm currently thinking, I downsize to just the 45 & 29 active (or possibly move it all from the 45 to the 75), I'll need to get rid of a
Pacific Blue Tang,
Coral Beauty Angel, and Oscellaris clownfish. Plus one of the 45 or 75 setups with the rock currently in the 75. I haven't decided what to do next with the 125 and its fully cycled and healthy sand/rocks/inverts.
Any thoughts from other club members on things I should keep in mind? I do plan to potentially start up a big tank again in the future, but probably not for a year or three.
