I've been to the chat room and gotten some help but I thought I would put a thread out there...I have a 75 gallon tank that got ich when i brought a new african cichlid home. I treated with rid-ich (I have clown loaches) and followed directions. Overall treatment for about a week with water changes everyday and temp at 86degree. All signs gone, another water change was done then carbon added back 3 days later. No fish loss. Two weeks later ich again, now about 4 or 5 fish infected, clown loach covered!!! Started treating with cure ich. Been treating for 4 days, water change after 3rd day, not hardly any improvement, carbon out and temp at 86degrees. Lights are left off. Is this just an extremely stubborn case or what? Should I keep treating with meds or some people in the chat and an article I read on here said salt......Both the rid ich (what I used the first time and thought it was gone) and the cure ich use malchaite green and formalin. Any thoughts out there? My fish are tolerating the meds and temp ok for now....I'm scared it's never going to go away! Even if the signs are gone like last time how can you be sure?!!!!!!! Thanks
