Day 5: Complete water change for the 3 gal sick tank again. Added a little Prime and 3rd dose of
Kanaplex +
Furan-2 +
Metroplex. Tang is alert and watchful when I'm near the tank now; it does not go into immediate hiding like did the first day in the sick tank. According to Humblefish's thread
https://www.reef2reef.com/threads/treatment-options-index.247573/ and all the good advice from R2R responders, if the problem is ick or velvet, the Formalin dip should have helped. If it's brook or Uronema, the Metroplex it likely helping. I remain hopeful to save this fish.
In the MD, the largest banner fish is showing visible signs of of illness now. It's barely visible, like a fine sprinkling of white dots on the body, but it's there. I can only see it on the fish when it hits the light just right. I've looked at so many pictures to try to id, my mind is reeling, and I'm still not sure. All I know at this point is I'm fairly certain the problem came in on the snails I added to the tank without quarantining.
Now with a visible sign of illness and not just scratching on objects in the tank, I can't wait and continue the current course of treatments using the Kick Ick and Rally. Instead, I removed as many snails as I could find (two turbos still in tank somewhere that I couldn't locate and possibly a few cerith snails that the dragon wrasse missed). I then added CopperPower to the tank to support the fish until I have a day off of work to break down the tank - again.
Here's the plan...
I will leave all fish right in the 180 and treat them there (too many fish to put into separate sick tanks at this point). I'll remove all rocks, sand, decorations, etc., on my next day off and put them in the empty 75 gallon. At this point, I will bleach the heck out of everything. I'll run the 75 gallon until bleach does not register during testing for ammonia anymore, and then I'll do a complete water change and dose liberally with water purifier. I'll run a circulation pump and an air stone to recycle everything right in the 75 gal tank. Once everything is fully cycled again, and after a minimum of at least 72 days, I'll transfer everything back to the 180 gal. The fish will be treated in the bare 180 gal with some PVC pipe for hiding while the rock and decorations are recycling.
I have some questions. Will the sand clean up enough in the bleach bath to reuse? I have so much of it. I hate to throw it all away, but if you guys/gals think I should....that's what I'll do.
Also, is there a way to keep the 180 cycled without compromising treatment? I can't use Prime with CopperPower. I wish I could just treat with CP in the tank instead of CopperPower, but I have too many wrasses.
Thoughts or suggestions, please. Many thanks for your support!
