Sorry, I was off on the temps. Couldn't remember if it was 70-75 or 80-85 so I erred on the side of caution. That's great the water is clear but it might just mean he didn't have any on his body. Totally up to you but if you think you've got mights, I'd clear out the current bedding/substrate, treat the tub(s) with PAM per the directions and start over with new substrate.

Replace and repeat the above for the next month or so, once a week, and hopefully you'll have killed what ails him. The eggs are the hardest thing to get rid of and take the longest, hence the length of time. That's what I've done and it's worked for me...someone else might have a better suggestion. Good luck!
