Oh Charlie..... I knew this day was gonna come. So I have good news and bad news. Let’s get the bad out of the way first. I randomly ran an ICP test just to see where the system was at. It came back that my sg was 1.0285! For some reason, the calibration fluid I have been using for 3 years with no trouble suddenly increased!? I threw that bottle out and ordered 2 new calibration fluids and tested them against each other to make sure they match so that I always have a good solution. That problem is fixed now.
At the same time, I was having a bad cyano outbreak. As I’ve mentioned before, I really try not to add anything to the system that you can’t test for. I don’t do aminos, trace elements, etc. I just feed the fish and depending on where my nutrients are I may dose a bit of Benereef or Reef Roids. But, this cyano was really getting out of hand so I decided to dose Chemiclean. I have had good success with it in the past, even with Speciosa in the system and never had any troubles. Well, that wasn’t the case this time. I have had several corals bleach (but not die) in only 2 spots in my system. 1 was where the Cpt. Crozier, Flaming Sunrise, Jumanji and Mr Freeze sit. The other was where my Avengers, Fruitloops, Insanity, Prom Queen sit. They have all lost color and are struggling since the Chemiclean. Everything else in the whole 2 tank system has never skipped a beat. Since the WC after the Chemiclean I have even added a Brain Freeze and another Mr. Freeze and both of those corals are doing fantastic as you can see below. So I am extremely annoyed, frustrated and a little ticked off. This hobby can be really humbling....
Now the positive, The Jumanji and Legoland do not seem to have been phased by the issue. Both still have nice color and decent PE. I’ve got some other pieces cooking that don’t seem to be effected either so, let’s hope it stays that way. During this whole fiasco, I realized that I have never had any bleaching issues in the tank that uses the T5 hybrid. Although I don’t get colors as nice as over the Ocean Revives, the corals are extremely healthy and have done nothing but thrive. So, I am beginning to wonder if there is not a hot spot in the blue spectrum in those 2 locations under the Ocean Revives that are causing my problems. 2” away for these “bleached“ locations, corals are fine.....
Enough of my babbling....
These 2 are struggling pretty bad
This is my original Mr Freeze. Definitely a bit bleached out, but still alive and looks to be trying to heal along the growth edge
These 2 were added after the Chemiclean. They’re thriving!
