Well... The battle with algae and aiptasia seems to be over now, but the casualties were pretty grim. The modes of attack I used were long periods of darkness, no food, and moving stuff to my main tank.
No food: The wrasse jumped out of the tank while I was at work, just a few days after the last post, so there's nothing to feed. No worries here, but it tells me that in the future if I need to cut back on the feeding, I should move the feeders to the big tank first.
Darkness: This seemed to be very effective in fighting the hair algae. The zooanthids and GSP didn't enjoy it at all though. That led to...
Moving stuff to the main tank: It's a 150 gallon reef with 250w MH, so the transition was fun both ways. The Klines Butterfly kicked some hiney on any aiptasia it found, and either the butterfly or the blennie took care of the hair algae that hitched along. Unfortunately, I think the butterfly also enjoyed sampling the zooanthids.
Results: Everything moved to the main tank (that survived) is now back in the nano. Everything that was left in the nano has been cleaned up as much as I could. No sign of aiptasia, and very little algae is left. Lights are back up to the normal cycle and the normal 3g water change each week has continued pretty much unaltered throughout. The micro-fauna seemed to be unaffected by the whole thing.
Here's the tank as of Oct 29th:
I'll be posting more images as things progress. The surviving zooanthids are opening up nicely again, and will hopefully spread out to the pre-war stage.
