Unfortunately when I first set up my DT about 4 months ago I didn't heed all the warnings about using a quarantine tank. I paid the price by introducing a Midas Blenny that was carrying Ich. I decided to move my three fish out (Midas Blenny, Eible Angle, Blue Chromis) into a hospital tank to treat for Ich with hyposalinity while my DT remained fishless. The fish weren't in bad shape at all....two of the three showed 1 or 2 spots at the most over several weeks with very little flashing. They were all eating fine. I was concerned about having Ich in the tank and introducing new "stressed" fish down the road.
Anyways, fast forward to last night. I set up the hospital tank using a HOB filter seeded with material from my sump. I used the same saltwater mixture I use to do water changes which was mixed with RO/DI water the day before. SG, PH, and temp all matched my DT. I caught all three fish (was as stress free as could be expected....I used a temporary glass partition to keep them all to one side of the tank which made removal relatively easy), put them in, and woke to find both the Angel and Blenny dead this morning. The Chromis is still alive but breathing heavily. I checked SG, PG, temp, and Ammonia again and everything was in check.
Any ideas what could have caused this? I know it is recommended to use water directly from your DT but I assumed my water change water would be fine? The TDS meter is reading 0 coming out of the unit that was used to mix the salt. The aquarium, filter, and heater were all new. The only thing in the hospital tank was some PVC for hiding places. Any ideas? I am concerned about added any fish to my quarantine tank in the future if I can't keep them alive overnight. :cry:
