I have a waterfall in my pond, is that enough aeration? | Decorative Ponds & Water Gardens Q&A

I have a waterfall in my pond, is that enough aeration?
Robert – Racine, WI

Waterfalls are one of nature’s greatest creations. In addition to providing breathtaking beauty and places for daredevils to kayak and – for some inexplicable reason – ride over in padded barrels, they serve as massive aeration systems, introducing fresh oxygen into the ecosystem that fish and plants need to thrive. In backyard ponds, waterfalls serve many of the same functions – but their scale is often inadequate to provide sufficient aeration. They also fall a bit short as places for kayakers and barrel riders to strut their stuff.

So, while your backyard waterfall definitely helps to keep water oxygenated, additional aeration is always helpful – especially when algae begins to grow, and fish are faced with warming water and reduced oxygen levels. To provide the aeration any backyard pond needs, we strongly recommend our KoiAir™ and PondAir™ Aeration Systems. With a wide variety of options available for ponds of every size and depth, these systems help to increase circulation and reduce stratification to provide the healthiest possible environment for fish and decorative plants.

For signs that your pond’s aeration is insufficient, look for increases in muck and debris at the pond bottom. When properly aerated, muck is broken up naturally, leaving the bottom clean and the water clear. If you have fish, and they surface regularly or gather beneath a waterfall, your aeration may be inadequate. If that’s the case, you’ll give your fish cause for celebration by installing additional aeration – and you’ll have the satisfaction of a clean, clear pond that makes your backyard the perfect sanctuary.

  1. I also have a backyard pond with a waterfall feature in a home I recently acquired. The pond is around 600-700 gallons and has no filtration system. It has the typical rubber liner with enormous limestone slabs surrounding it. The waterfall runs around 16 hours a day on a timer. An image of the pond can be seen here: http://gallery.mac.com/jfelbab/100223/PICT1549/web.jpg

    There are no fish and a couple lily pads in pots. The pond is mucky on the bottom and the water is clear but string algae is starting to form as the temperatures now hover in the high 80°’s. There is a quarter inch layer of muck on the bottom of the liner which I can’t seem to reduce chemically.

    I’ve been trying Tetra Pond Algae Control, Oxy-Lift Defense Pond Cleaner and EcoSystems AquaClearer Extreme with little effect.

    I have another issue as well. When the water evaporates, I need to add water from my well which is loaded with iron. This stains the limestone with rust, especially where the waterfall flows. A pressure washer doesn’t remove the rust stains. Since I don’t have any fish, I guess I could try a rust remover product of some type but I’d like to find a product that would eliminate the rust stains from forming in the first place. I’d also not want the water to become poisonous to wildlife that drink from the pond.

    I need to find a solution to this pond problem. Any and all tips would be appreciated.

    • Pond Logic® Water Conditioner makes tap water safe by removing chlorine and detoxifying heavy metals. That being said, your rust rings should be prevented from developing. Pond Logic Water Conditioner is great for treating new ponds or for use after performing water changes.

      A filtration system is highly recommended for all ponds. With a pond this size, we recommend The Pond Guy Clear Solution 4-in-1 Pond Filtration System. While providing proper filtration for your pond, it will also provide UV clarification against algae. Although a UV light will only treat the algae that passes through the light, not string algae, it will help to combat future algae attacks. To treat string algae, an algaecide will be the best defense. After you have completed your last treatment of algaecide, wait 72 hours and begin treating with Muck Defense to help rid the pond of the excess muck accumulated at the bottom of the pond which algae thrives off of. Helping to remove this muck will also help cut down on your algae problem.
