how quickly do you see improvements? This is day 3 for me and not seeing much improvement yet.

Ich medicine can only kill the ich when it’s free swimming. The ich rotates in a life cycle. When you see the white dots on your fish there is ich feeding on your fish’ skin. The individual parasite leaves the skin eventually falls to the substrate and multiplies. Then all the new parasites release into the water looking for a fish(free swimming stage) and this is the only time they are vulnerable to medicine. This whole life cycle takes multiple days probably a week. So I’m not surprised you don’t see improvement after 3 days. Just making this comment so other people will see this and be informed that ich is a lengthy treatment and it doesn’t matter what medicine you’re using because they’re all only effective when the ich is free swimming.

does this only kill the ich that is on the fish and not the cysts that lie in the gravel

It does not kill Inch on the fish or the cysts in the substrate. It only kills the swimmers that hatch from the cysts. That is why you must go thru the complete cycle.
