Any water can contribute to ick or cloudiness, depending on what is in it. Well water is not necessarily bad water, and filtered water just usually means the hardness has been removed, but not necessarily all of the pollutants. Ick is due to stress or fluctuating temperatures in the tank. Test your water for pH, ammonia, nitrite, nitrate, and alkalinity to see if you have the proper water quality or not. If not, do a partial water change and add Tetra Aquasafe Plus, wait a few minutes, then add Tetra SafeStart Plus to help reduce ammonia or nitrite. Aquarium salt will also help. If it is fine, then simply treat the fish for ick with Ick Guard or Parasite Guard. Both are effective products.
