Does Your Pond Contain Proper Levels Of Dissolved Oxygen?

Posted by Heather Newhart on

Many things add air to the water like waterfalls/streams, fountains, plants, wind, but is it enough? Tricky question!!


In general, most large ponds are under aerated. This doesn't mean your fish are dying! Your fish can absolutely survive in your pond as is. Fish can live in very low oxygen environments. It is common that the top 3-4 feet contain oxygen, but the deeper water does not.

So what causes fish kills? A slight change to the water can make a dramatic shift in the oxygen level. The low levels that normally do not bother fish, can turn into a crisis situation.

Although waterfalls/streams and fountains add some oxygen through the movement of water, this usually doesn't create adequate levels of dissolved oxygen. Plants provide oxygen during the day, but consume oxygen at night. Underground springs contain little to no oxygen.

Treating pond water with a chemical algaecide or aquatic herbicide can cause oxygen loss from water as the weeds/algae die. Large algae blooms & weed growth that cover a large portion of the pond can also consume oxygen. Green water is especially notorious for major oxygen consumption. Weeds and algae produce oxygen in water during the day, but consume oxygen at night. Temperature rising in water also decreases oxygen levels.  Any one of these things could push a pond with low oxygen levels to the breaking point.


Your answer- Bottom Aeration. Increasing oxygen levels by using an aerator to boost dissolved oxygen levels will help your pond in so many ways! Increases oxygen in times of need like hot water and chemical treatments. Aeration is very inexpensive to run 24/7. Aeration also increases the amount of space where your fish can live in your pond. This can boost your fish health and population growth.

Pond Ice Safety

Be sure to measure the ice thickness before each use!  Turn off pond aeration systems or relocate diffusers to shallow areas that will not be used for on-ice activities.  If the pond routinely has flowing water use extreme caution because flowing water can cause differential ice thickness and weak spots in the ice.Stay away from [...]
