When do the bacteria say it’s too cold to eat? Farrah – Rockport, KY
You’ve counted on your bacteria to keep your pond clear and muck free throughout the summer but they may soon be taking a breather as winter approaches and water temperatures drop. Although you will see a dip in muck eradicating productivity rest assured that your microbial mates are not saying goodbye for good.
Bacteria products like Pond Logic® PondClear™ and MuckAway™ advertise that you should apply treatments whenever your water temperature is above 50°F. This is more of a target area than a temperature cutoff and lets you know you are approaching conditions that are less than optimal for your bacteria to work. Once your water temperatures frequently stay at or below the 50° mark you will want to stop applying bacteria treatments.
To monitor this target area, you can install a floating pond thermometer in your pond to take regular temperature readings. To get accurate readings push the thermometer beneath the surface of the water and closer to the bottom where the water is less affected by ambient air temperatures. Be sure to remove the thermometer before your pond ices over to avoid damaging the unit.
Your bacteria may not be too enthusiastic about the cold weather, but your other pond care products like pond dye are ready to go no matter what the forecast says. As some plants can still grow in colder temperatures while your bacteria and herbicides are out of commission, dye can be one of the cheaper and easier applications to help maintain your pond even as it ices over.
