i am not familiar with that particular product, but most bottles seem to have inadequate instruction on them, i suppose so if it doesn't work quite right, you buy more meds? eeek...anyways, it is important to clean your gravel when changing water to remove the ones that have fallen off--do some reading about the ich life cycle on the net--put in a search for 'ich' and freshwater fish--in short, they grow on the fish, fall off, and reinfest--rate of growth is affected by water temperature mostly, and most medications have methylene blue or ?malachite green?--i had some once with copper products in it, but avoid those for now...not sure about your particular fish, but most infestations of ich can be killed with salt added to water, but you definately should find out about your particular fish's tolerance of salt--and NOT table salt! kosher works just as well as aquarium salt....anyways , the little 'ichlets' are only vulnerable to treatment at the free-swimming stage, so you must continue treatment longer than most bottles say to anyways, longer the cooler your water is of course....aside from calling your particular manufacturer directly or finding their website, you may have difficulty finding specific instructions for that medication--in that case you may have to use your best judgement--research the ingredients in the med and it's effect on your fish, observe your fish carefully after administration of medication for any signs of fish stress, and vacuum the gravel frequently--i usually do it about every other day if i have to deal with the ichies, which thankfully is rare! you should also try to determine the underlying cause that made your fish susceptible to ich in the first place, so you can avoid it in the future, as ich is almost always present in the water, but the fish can naturally fend it off to a point if other conditions are favorable...common causes are swings in water chemistry, high ammonia, high nitrite, new additions to the tank, a bully chasing others, etc--anything that will increase the stress level of your fish...and as methylene and malachite tend to stain seals in tanks, and i try not to use any more chemicals than necessary--i fully recommend the salt treatment when at all possible-- keep that in mind in the future if your fish can tolerate it--much cheaper and easier on the fish ...
