Found one of my silver's with fin rot today. Water is 0 ammonia and nitrates. 3 ppt salt. Ph 7.6.

Other silver's in system seem fine. This was a bigger silver amongst small ones.

Any ideas? I've taken it out of the main tank and put in a hospital tank at7ppt salt.

Found the timer had intermittently stopped on this system last week end so could have been low do stress. Second timer to fail in a week:-/ now using digital timers as don't trust mechanical ones. Had 3 fail in a year!


Don't think he'll make it. May put it out of its misery.

If you can isolate him... yes a salt bath at 10ppt for an hour (well aerated)... and return to 6ppt for 2 weeks...

If you can't isolate.. then either salt to 6ppt... (3ppt is just for Ich)... or eat him...

Banged him on the noggin and Fed him to the compost monster. He fell over soon after isolation. He was moved about 3 week's ago and came from some poorly treated stock that had fin rot about 8 months ago so maybe he was a bit weak? Putting lots of air into the others as a precaution.
