I actually have a question. I'm using the med trio for the first time and not really seeing how to use the ICH - X for quarantine. the directions say "for as long as symptoms appear" but because i'm medicating for everything before the onset of symptoms, i'm not sure how i should dose the Ich-X. Do I use just one tsp on the first of 6 days? 1 tsp every day for 5 days doesn't sound right because i need to do a 1/3 water change before each additional dose of ICH-X but that conflicts with the maracyn and paracleanse which require a 25% water change on the 6th day only. I'm way overthinking it.
