Jets and sprays are welcome additions to ponds because they look great. But if the designer or installer follows a few key guidelines outlined here by Roy Watkins, the list of benefits will expand to include an overall improvement in water quality and a healthier environment for fish.
In a well-balanced pond, the oxygen content of the water is seldom an issue. But if things move off course, notes Mike Gannon, it's essential to find the cause -- and then apply one of three possible remedies tailored to the urgency of the need and the extent of the budget.
As the watershaping industry gets more involved with naturalistic bodies of water - particularly large ponds, lakes and streams intended to harbor life in the forms of aquatic plants and fish - it becomes increasingly worthwhile to understand the important role of proper aeration. Aeration is a simple process involving the injection of dissolved oxygen (DO) into water. Nature aerates by way of things such as waterfalls and rain - activities we must imitate by mechanical means in our man-made settings if fish are to be healthy and a host of water-quality problems are
