Pond Management Information

• That pH ranges between 0 and 14? Water with a pH value of 7 is neutral, below is considered acidic while above is alkaline. pH levels between 7.2 and 8.5 are considered acceptable in pond applications. Aquatic plants can affect pH levels during photosynthesis periods (daylight hours) opposed to non-photosynthesis periods
  (night hours) when pH levels can drop considerably.
• That Water Circulation is perhaps the most important characteristics of any filtration system? In an aquatic application, water circulation suspends solid waste and carries it to the filter where it is captured.
• That no pond filter is "maintenance-free" and that all filters require some level of care? Filters left unattended can quickly become over loaded with waste resulting in fouling. Decomposing organic waste depletes the dissolved oxygen level and affects overall water quality in the pond and can potentially be harmful to fish.
• That pump performance is greatly effected by: "Head Pressure" and "Line Pressure"? Head Pressure is the vertical distance the pump is required to operate at. Pumping water though a long run of pipe through tee and elbow fittings creates pressure on the pump. This is termed "Line Pressure".
• That ammonia levels are affected by decaying uneaten fish food, waste and respiration? Too many fish in a pond and overfeeding mean that wastes produced can exceed the capacity of nitrifying bacteria colonies. Fish suffering from ammonia toxicity typically stop eating and become lethargic.
• That the size of a pond and its filtering capacity establishes its maximum "fish density"? Over-stocking a pond with too many fish will exceed the filtration capacity and jeopardize the pond's water quality... ultimately affecting the health of your fish.
