Thanks Jamie. I'm having a little issue with two SPS that I put on my favorite list a long time ago. It seems like any coral that I really like is the one that is absolutely going to go first, if something is off.
The Tyree frag looks much much much too light for the past few days, and the A. Secale is faded as well. The tyree was that bright purple coral a few months ago, and at this point only the tips look right, while the coral's core and branches look brown and mottled. The A. secale (that I jokingly referred to as Melev's Purple Monster is also quite faded, though still somewhat lavendar.
I tested the alkalinity because I had a feeling that was the culprit, and the test results read 14.8 dKH. Since the range is 8 to 11 typically, that is quite a climb. I turned off the CO2 going into the calcium reactor a couple of days ago, and did a little 15g water change as that is what I had on hand. In the meantime, I have 85g of newly mixed saltwater ready to use now.
Today, alkalinity tested 11.2 dKH, so the CO2 is staying off for another 24 hours. The reason I turned off the CO2 is so the calcium reactor wouldn't release any further alk into the system. I'll test the calcium levels in a little bit, and buffer that if necessary. 390 to 450 ppm is the recommended range, and hopefully my tank is right there.
The Tyree frag looks better today than it did 48 hours ago, but only if it can hold on will it heal up. I had an offer to frag a portion or to move the entire coral out of the system, but I was concerned that the move would be just enough to push that coral over the edge.
All the rest of the corals look very happy and healthy. The fish look good. A little cyano plagues me as usual, and my procrastinating regarding Chemi Clean is the problem. I should have ordered it two weeks ago, but haven't. I wish I could buy it by the barrel. :lol:
Carbon was replaced today. The prop section is full of happy corals currently.
