Sorry, I haven't posted an update in awhile. The work and the stress continue....
The video by melypr1985 was very helpful. Thank you for posting! I managed to FW dip several fish from different tanks. Unfortunately, I could not catch one of the blue lined wrasses in the 75 gal, but I did dip the yellow tang from that tank. I saw it scratch against one of the PVC pipes the same day I did the dip. There were some tiny floating particles in the water after the dip, but not many, and not nearly as large as what was observed in the video. I did not see any come off the fish's body like I saw in the video. In truth, the particles could have come from the tank as I scooped the fish into the net and then transferred it (and particles) to the dip container. I feel like the dip was inconclusive. If anything did come off the fish, my guess is it came from the gills of the fish, not the body. I watched the fish very closely for the full 5 minutes.
I have finished a month plus of CopperPower in the 75 gal and did a 40 gal water change today without adding copper back into the tank for the first time in over a month. I think the fish are too stressed for another round of copper at this point, and it does not seem to be working against whatever is still ailing the fish. I finished two rounds of the Furan2 treatment without success in curing the infection on the yellow tang too. I'm still dosing food with the MetroPlex, KanaPlex, and Focus. The fish hate the taste and don't eat it very well. I'm using garlic guard to try to get them to eat a little better. I lost my flame hawk two days ago from this tank. I don't know if it died from the many treatments I've been doing or if PuffDaddy, the porcupine puffer, decided he didn't want to eat the crappy tasting food anymore and bit its head off. Whether PuffDaddy bit its head off while it was alive or if he did it after it was dead is in question, but either way, I got up to another heartbreak in the morning - a dead fish.
I don't think the treatments are working well. I plan to give the fish in the 75 gal a few days of rest from copper, then dose with General Cure. I will continue with the MetroPlex and KanaPlex for another week.
I also dipped two fish from an untreated main display tank as I saw some fish scratching in that tank now. I'm worried that whatever is in my other tanks is in this MD tank now too. Gawd help me! The tanks are set up about 4 ft from each other. What was I thinking! I didn't know about contamination through the air then. I saw about the same results with fish from this tank as with the yellow tang from the 75 gal...nothing visible coming off the fish but a few white specs in the water after the dip. When a sick tank opens up, I think I will treat with General Cure all the fish in this tank too, just to be on the safe side.
The 29 gal CP sick tank with the majestic angel was dosed with Furan2 for 10 days. I am continuing to feed the MetroPlex and KanaPlex with Focus in this tank too. The angel hides a lot, but continues to survive. The CP comes out in another week. I have not dipped the majestic angel yet. It's still so stressed; it hides most of the time. I'm thinking I might just treat with General Cure when I finish the CP treatment and skip the dip.
I continue with water changes every two or three days, daily monitoring for ammonia spikes, and visually looking for signs of stress and/or recovery. The only upside is I no longer have to monitor for copper levels anymore.
After I treat the 75 gal with General Cure, I have to decide if I should try treating the tank with CP in hopes of killing whatever won't die in the copperpower. I will have to figure out what to do with the wrasses and other fish that won't tolerate the CP treatment. Any thoughts about this plan of action? Am I doing too much...not enough? In truth, I'm exhausted as I need to do all the water changes carrying buckets. I don't trust that the hose I used to use is contaminant free.
