I'd say it's going poorly! I tried the special blend. I overdosed per the instructions on the box (instructs to overdose for saltwater). I also ran carbon for 3 weeks during that time. Special blend didn't seem to help. I tried a 3 day lights out with trash bags taped to the tank. That seemed to help quite a bit, but I believe I had some light getting in through the back corner a bit. My corals started to get affected a tiny bit, but not much. You either kill this stuff completely or it comes back fast, so I'd say I'm not winning.
This week I started running GFO instead of carbon and I've been keeping the Ph up using Kalkwasser, but I'm traveling next week and will just have to let the tank go on auto pilot other than feedings. I think once I get back from my trip I'm going to keep the Ph up consistently for a week or two and try a 5 day black out if I get that desperate. If that doesn't work, I'm going to hire a LFS, maybe SS to see if they can help solve the problem. Hope your fight goes better than mine. I feel like I could use a dino support group.
