Metroplex in water

[Bill]

I know it would be better to use in food, but if a fish isn't reliably eating has anyone used Metroplex in the tank water as described, and successfully treated parasites like hexamita, as in a definite improvement after treatment?

Not specifically that med, but we always recommend treating the water, and not the food for this reason. Fish stop eating with internal parasites, and don't get the med. In addition there is no way to know how much med the fish gets if it does eat the treated food.
