Okay, I HAD a sorority in my 10 gal tank. I QT'd the newbies. They seemed healthy, added them to the tank. This morning I noticed the newbies were hiding A LOT. and then I noticed pine coning and popeye & white poop.
The 3 newbies were removed & died. That was sudden.
Somehow someday my alpha female who I had before the newbies *seems* to have not caught any parasite the others had. As a precaution, I removed her and gave her clean water. I use vinegar and water on EVERYTHING- tank, gravel, decor, filter, and I threw away the filter cartridge. I put in all clean water, maracyn two and 1 tsp/gal of Epsom salt. (she's in her 10 gal tank but i only fill it to 7 gal so I added medication and ES based on 7 gallons.)
My question: what % and how often water changes should I do? Correct me if I'm wrong, but I'm assuming I add ES to each new gallon of water after performing water changes. Note the maracyn 2 should only take 5 days of treatment unless she looks sick/sicker.
ALSO- the maracyn two says to perform a 25% water change after full treatment is done. I'm assuming that means I should NOT remove 100% of the medicated water?
Any extra tips are welcome- even if you think they're obvious I might not know. Thanks!
