Arthur Bryan Cooper (Arthur B. Cooper) is an established small business leader with extensive experience in the residential landscaping sphere. One of Arthur Bryan Cooper’s areas of focus over the years has been aquatic landscapes, including those incorporating koi ponds and rock waterfalls.

One common issue with koi ponds is that sometimes not enough oxygen is introduced back into the water for the fish to survive. Waterfalls fulfill this role by constantly churning and aerating the water and replenishing the oxygen supply koi depend on.

For ideal filtration, the entire contents of the pond should be pumped each hour. This means that a 4,000-gallon pond typically supports a 4,000-gallon-per-hour waterfall, depending on pump and filter setup. This is approximately four to five times the quantity of water a standard garden hose can deliver in an hour.

In addition to aerating the water, a waterfall often integrates a spillway at its base that effectively camouflages the filtration system. This creates a base for a pool of water at the waterfall top, without any need for additional liner. With the biological filter concealed, the pond and waterfall blend harmoniously with the natural environment.
