Can I go from a treatment of Prazipro to the trio with just a water change? I can never find information on how to switch from one med to the other. You're always told to switch meds but never how, like should I always use carbon or not. Some of my cory's are flashing and sometimes my oto's dart off. I'm guessing parasite. I treated with ich-x for five or six days. Then I treated with prazipro and realized I left the carbon in after the ich-x treatment. So I did another round of prazi pro. Today is the fifth day and they're still flashing. I thought about just using the trio or maybe just paracleanse. No visible signs of anything other than flashing.
