Ive done roughly 80% water change but the fish still look bad. Not sure if it will take time for them to recover or theyre too far gone. The naso seems to move around every now and then so maybe its not too far gone. Not sure what more I can do. Ive added a dose of prime just now for an emergency fix so lets hope for the best. Will also add a bit of bacteria and see how it goesThe consensus on this form is it does help much. Beyond a day or just hours and ammonia is right back and possibly even higher once prime is gone. Ammonia is not going anywhere with prime, is just gets coated for a moment when prime is used.
With all this said, a WC is your best best and dose bacteria. I have personally tried prime almost two years ago and nothing worked in the QT tank at the time. I resorted to simply doing WC’s.
