LOW OXYGEN AND POND AERATION William A. Wurts, State Specialist for Aquaculture Kentucky State University Cooperative Extension Program www.ca.uky.edu/wkrec/Wurtspage.htm Water can only hold a limited amount of oxygen. That is determined by atmospheric pressure, temperature and salinity. In a natural setting, oxygen is added to water by atmospheric diffusion at [...]

Toxic Blue-Green Algae Blooms in your pond - also known as Harmful Cyanobacteria Algae Blooms - can happen in your pond when surface temperature increases and excessive nutrients are available. Cyanobacteria is a prehistoric life form and is rather fascinating because it has the ability to make it's own food [...]
Cyanobacteria Harmful Algae Blooms (cyanoHABs) are occurring more often and in water bodies that use to be safe for dogs. It's not easy to determine if the cyanobacteria bloom is toxic by just looking at the water, laboratory testing is required. Assume it's toxic and keep your dog away if [...]
Water tends to attract attention. The gentle sounds of flowing water sooth our senses. We feel an automatic connection to the soft, rippling current and the mesmerizing creatures that generally come along with it. Incorporating a water feature, water garden or pond into your landscape can help you relax at [...]
Pond Maintenance: The Role of Bacteria Products in Your Pond Most indigenous microorganisms (bacteria) found in your pond fail to breakdown and remove difficult to degrade organic matter. These same bacteria may also be less efficient at reducing higher than normal levels of nutrients like phosphorous and nitrate. When selecting [...]
Garden Pond Construction: Rock Fountains This carved rock fountain would look beautiful in a garden with shade so the moss will continue to grow. The fountain rock is 59"long x 33"wide and 12" high and we estimate it weighs between 1000 and 1200 pounds. A pump is included to make [...]
This is one of several research articles that we have studied to learn how deciduous leaves contribute to increased levels of nitrogen and phosphorous in pond water. The author of this article is John R. Dorney and was published in Water, Air, and Soil Pollution 28 (1986)
Using a Secchi Disc to measure water clarity can provide useful information for keeping your pond healthy. A Secchi Disc is made of metal or plastic with contrasting colors that can be observed as it is lowered into the water with a string. A seldom used coffee or tea cup [...]
If you have a direct drive submersible pond pump and you are getting your pond ready for Spring it is important to check the oil level in the pump. Direct drive pumps use non-toxic turbine oil to lubricate the drive shaft assembly unlike magnetic drive pumps which require no oil. [...]
I took this picture after the ice just disappeared on this pond. Why is there so much live green algae? The most likely cause is the release of nutrients from the organic sediments on the bottom of this pond, no surface waters run into it. Along the edge there are [...]
