I’m starting my pond up for spring. Do I need to leave my aerator running? | Decorative Ponds & Water Gardens Q & A

Q: I’m starting my pond up for spring. Do I need to leave my aerator running?

Nikki – Glen Forney, PA

A:  As winter gives way to the sunny days of spring and summer, you should absolutely plan to leave your aerator running. That water-churning system that benefits your pond over the cold months will also benefit your pond during the summer—and then some.

Winter Bubbles
As most pond owners know, an aerator, like The Pond Guy® Water Garden Aeration Kit, used during the winter serves two purposes: to aid de-icers in creating and keeping a hole in the ice, and to circulate water to vent gases when filtration systems are shut down for the season. The circulation also encourages contact between the water and the environment, which will increase the dissolved oxygen level in your pond.

Summer Aeration
In the summer, aeration provides some extra benefits. Besides moving the water and boosting the oxygen level in the water molecules, aeration does these things:

  • Circulates the water in areas where filtration may not reach, preventing stagnation and low-oxygen pockets in your pond. Filtration systems only move the top of the water column, not the bottom. But an aerator works from the bottom up, circulating the water and increasing dissolved oxygen levels throughout the pond.
  • Keeps oxygen distributed throughout the water column much more efficiently than a water feature, like a waterfall, spitter or stream.
  • Provides bubbly camouflage in which fish can hide.
  • Stirs up debris on the pond bottom, allowing it to be filtered out or broken down by beneficial bacteria. If that debris is allowed to collect, muck will build up and release harmful gases as the organic materials decompose.
  • Helps beneficial bacteria thrive and flourish, thanks to the circulation and oxygen. Higher oxygen levels stimulate and increase the number of natural aerobic bacteria living in your pond. More bacteria means more efficient filtration.

As you’re prepping your pond for spring, jump start the season with DefensePAC® Pond Care Package. It contains Oxy-Lift™ Defense®, Nature’s Defense®, Clarity Defense®, Muck Defense® and Seasonal Defense® — everything you’ll need for spring cleaning, bacteria boosting and water clarifying.

Aeration definitely has its benefits, no matter what the season. If you want a balanced ecosystem with healthier fish and plants, keep your aerator running.

Be Aware of Oxygen Levels When Treating for an Abundance of Algae – Pond & Lake Q & A

Q: My pond was almost completely covered in algae earlier this month. With the advice of a local store, I treated my pond with an algaecide. Needless to say I suffered a terrible loss! What killed all of my fish? – Marie of Florida

A: More then likely your fish loss was due to oxygen depletion. It is very rare that an EPA registered “Aquatic Approved” chemical will cause a fish kill.

What causes oxygen depletion?
After a chemical application, algae and aquatic vegetation start to die and begin to decompose. The decomposition process requires great amounts of oxygen and can sometimes, like in Marie’s case, be harmful to fish. The chance of oxygen depletion is much greater when a pond is not maintained on a regular basis or when water temperatures are at their warmest such as the dog days of Summer. The warmer the water, the less oxygen it can retain.

How to treat your pond and keep your fish safe:
We recommend that you treat your pond in sections. The generally rule of the thumb is to split your treatment in to 3 parts or thirds. Treat 1/3 of your pond starting from shoreline working your way towards the middle. Allowing 5-7 days between treatments will greatly reduce, if not completely eliminate the chance of fish kill.

NOTE: Always follow the label rates on the container!
