yeah thats what i plan on doing. the reason im not changing the water now is because i still have the meds in the tank. once im done with the treatment, should be tomorrow, i will change the water. at this point, if i am correct, there should be no more ich free floating. the only thing that should be in the water column is coppersafe which i will have to do many water changes over time to remove. thats in my schedule once i finish ich treatments completely. i hate ich.
Ich may be residing in the gills still but unlikely. Also may be in the sand, hopefully catfish movement will stir it up and expose them.
