Aquarium Advice FINatic
I would like to know how long should I keep cupramine in my tank for in order to kill off all parasites. I have tried it for several times and the longest it was done for was 7 weeks. Please let me know since I just keep getting this now for the last 3 month's. my water parameters are all good and I have a filtration system that people will kill for. please let me know, if anyone can help.
