Week 3 Complete!
Bubble Algae - Approximately 75% gone. What remains is on the bottom 1/4 of the rockwork, which supports the theory that the medication is more effective in areas that get the most light (and perhaps flow).
Livestock - Several stressed corals (losing color, closed polyps, “deflating”). Specifically, a couple of acans, two euphyllia (hammer and frogspawn), and two cyphastrea. Other corals (other LPS and Zoas) are fine.
Nitrate - Now at 10+ ppm, and may be why the corals are stressed, rather than the meds, per se.
I am going to pull out some of the rocks and scrub them the best I can in a bucket of tank water. I am very concerned about the nitrate level, and will do a 25% WC. I wish I could let the meds have one more week to work, but I’m not willing to risk it.
