Flukes. I have tried everything I can think of to eradicate flukes, but mine are bionic. The last effort was with MinnFinn, and after two separate series of treatments, it's NO SOAP.
The reason I didn't use Potassium Permanganate is because with all the sand in the 125 g, and 2 canister filters, I could never keep it viable for longer than about 20 minutes, due I think to high organic load.
So, now, I have to sterilize everything. I'll remove the sand and make it a BB, remove and sterilize the canister filters, hoses, and see if I can get the PP to remain viable for the 4-hours required. I can condition about 130 gallons every night, so I can change all the water in the tank daily.
Without filtration, but with a 90 - 95% WC daily for 2 weeks (treating with PP every 3 days), would the fish do OK, do you think? Or would there be too much ammonia buildup during the 24 hours between WC's?
Obviously, after successfully treating with PP, I'd re-establish the bio-filters.
