we recently had ick in our 30 gallon fish tank so i called my uncle and he told me to take out all the water,plants,drift wood and gravel and wash everything with soap so i did and now their is soap in the water. i don't have any fish in it right now because the ick killed them all. so i was just wondering if any body knows a way of getting the soap out of the water without having to take most of the water out.
