In rare cases, pink eye can occur due to overly dry eyes. For instance, you could end up with a nasty case of pink eye after a day of skiing if your eyes dry out due to over-exposure to wind and sun. If this occurs, you may experience a lot of tearing to re-lubricate the eye and flush out the bacteria.
You will notice a real boost to fish health and growth. Major water change: Simply drain the pond down 60-70% and add dechlorinator. Then refill the pond. Donât do this in the PEAK of the summer as you might chill your fish. But SURELY in the early summer and late summer you should find the fish VERY appreciative of this service.
Check for the cause of any cloudy water. Scoop pond water up with a clean, clear glass jar. Put the jar of pond water in sunlight for 4 to 5 days. Algae will move about constantly in the water and will turn the sides of the jars green or brown. Silt will all settle at the bottom of the jar and will not move about. Treat the pond for excess silt. Throw in 100 lbs. of hay to treat silt caused by clay soils.
