while we're on prazi, i just finished one five day treatment in the DT for worms-- I spotted them in one tang's poop, medicated, then all three of my large tangs voided HUGE amounts of worms about two-three days after treatment. I have not spotted any feces in the last day or so.
Did a good solid fuge cleaning and 25% water change today (and turned the protein skimmers back on, which both went crazy before the WC was done).
Should I do a second five-day treatment? Am reluctant to, just because I have to turn off the protein skimmers, remove carbon and other resins, and the tank gets.. well... that hard geen algae you have to scrape off.
But if a second course is needed to be sure the worms have been summarily dispensed with, I will do it. And spend the week mixing up another massive supply of saltwater.
