I have had some bad luck this summer and haven' posted all of my updates. Back in June I lost some fish to an ammonia spike that I never figured out, I got a clogged overflow between the systems in July which dropped my salinity to .022 over night and flooded my garage, I had a punch of tissue loss due to that later and I discovered a montipora eating nudibranch which wiped out a small colony. So I have had every problem this summer and it's all been documented on my local club thread. After going through some macros I shot last night I have discovered red bugs on my red dragon and tri colors. I saw some on a few millis as well.
I have way too many encrusted acros to dip everything and Interceptor is not available. While I have Sentinel, I don't want to deal with the invert/copepod kill off and it's not well documented like Interceptor is. I've decided to drop that tank slowly today to 66° which is also known to kill them off but like Sentinel, less documented. However, I don't have to deal with water changes and carbon etc like with the medication. I thought I would have it down by noon today and would keep it there until this evening. It's now 3:30 and I'm still only at 71°. I'm not sure if I can get it low enough even with ice and swapping water to the freezer hourly.
I will probably lose some more SPS due to shock and tissue loss but I have already lost a handful of acros this summer and I have 2 massive colonies in trouble at the moment. So I'm rolling the dice. Wish me luck, I'm 1/2 way there.
