Waterfall Filters are often times used in conjunction with regular filtration systems and skimmer filters. They are both functional, and beautiful to look at, providing additional filtration and aeration as well, by breaking the water surface to allow for oxygen to be absorbed into the water.
Waterfall filters should be located on the opposite end of the pond from any skimmmer filter you may be using to insure for the best possible water circulation.
Waterfall filters are best used for biological filtration, since the media and oxygen-rich environment are perfect for fostering beneficial bacteria.
A key point to take into consideration is the size of your pump, to insure adequate waterflow through the waterfall filter.
Beautify your water garden with a stunning waterfall/filter combination.
