Carbon to get rid of meditication

[i3k]

OK, I have ICH outbreak in one of my tanks and I've been dosing it with Clout and removed the carbon filter. My loaches in that tank are having a bad reaction from clout. They are not moving and their skin got darker. I've been dosing for 3 days with temp. of 84 degrees and the Ich problem seems to be getting worse. So I want to switch medication. I have aquari-sol which I've had luck with in the past. My question is, if I put the carbon filter back in, how long will it take to clear out the clout medicine? When can I switch to aquari-sol? Last clout dose was yesterday morning. I put in the carbon filter back into the filter this morning.

Thanks.
