Pond aeration benefits over the long term

If you have a pond, no matter how small, you’ve probably been told a lot about pond aerators solutions .It can be difficult to know what’s nonsense or sales pitch and what’s genuine advice, however, so here’s some tips.

What does aeration do?

By maintaining healthy levels of usable oxygen at the bottom of your pond, you promote a healthier balance of aerobic bacteria and microbes. These in turn benefit you by cleaning up the muck and detritus that otherwise accumulates at the bottom of water features- extending the life of the pond.

That’s not where the benefits stop, though. Water clarity will also be better in an aerated pond, as much of what we perceive as ‘murk’ is caused by suspension of organic particles in the water. Again, aerobic bacteria will break down these particles, giving you better water clarity. In turn, you’ll decrease the weed and algae balance of your pond. The aerobic bacteria you’re promoting compete with nuisance blooms for available nutrients, and generally win. Additionally, they themselves form an important part of the fish food chain, promoting healthier fish with access to better nutrients. In particular, aerobic bacteria are good at eliminating phosphorous from the water- and phosphorous is a notorious algae feeder. Aeration also assists with binding phosphorous with iron, an oxidation process that relies on the presence of oxygen in the water and makes it impossible for algae to use.

Other benefits of aeration.

In a world obsessed with taking the green route, aeration of a pond can also eliminate or at least reduce, the chemical burden needed to maintain your pond. As mentioned earlier, it promotes healthier, happier fish too, as the not only appreciate the bacterial growth as a food source but also benefit from the oxygen layers in the water. Fish generally do not appreciate the hotter upper water of a pond, but are forced there when bottom layers of water become deoxygenated in non-aerated ponds. You want to watch for fish that swim towards the top of the pool in the early morning, as it’s a sign that there’s depleted oxygen reserves available to them. Algae blooms, cloudy windy conditions, heavy downpours of rain that churn the water and inappropriate use of aquatic herbicides can all result in conditions that will cause fish die off in summer. Remember that mosquitos breed in stagnant water, too.

It goes further than this, though. In winter when ponds ice over, it’s not uncommon for oxygen levels to fall in a pool as it’s sealed off from the atmosphere. Additionally, plant die back and decay will adversely effect the atmosphere. These hostile cold conditions can cause fish populations to die off.

An aerated pond helps avoid both of these scenarios, as it ensures a good clean circulation through the pond and the maintenance of good oxygen levels, promoting a healthy ecosystem that works for the beneficial organisms in the pool, from ‘good’ bacteria to your precious fish.
