My wINTER Pond Is DifferentYes, every pond is an individual when it comes to how it will act in the Winter, or any other time of year, for that matter. Differences include: age, size, depth, filtration, fish load, additional wildlife load, exposure to sun and wind, adjacent terrestrial plant life, amount and variety of the aquatic plant life, and a plethora of other micro-climate variations. Add to this how much fish food gets thrown in the water (any, a lot, none). It all goes together to make up the body of water that is your pond. CYA Statement: Every article or blog that we write is based on the rules that we understand in average circumstances in the Greater Phoenix Metropolitan area. Your pond is an individual, with a unique set of circumstances, so please understand that what we discuss in any of these articles is the rule of thumb and may not be precisely descriptive of what you are experiencing today in your own personal backyard pond. Fish and Water Temperatures in A Winter PondWith winter temperatures, as the water dips down below 55 degrees (water temperature follows the nighttime temperatures, NOT the daytime highs), we recommend you stop feeding your fish. In colder water, the fish don’t metabolize high protein food like they do in the summer, and if it goes through their digestive system too slow, it could begin to rot inside them and result in a fish kill. We get a couple of calls a winter from people who have literally fed their babies to death. It's a very sad thing to have to tell people. As always, natural treats like zucchini, melon, lettuce, oranges, and even Cheerios, can be given. Algae Blooms in Winter Ponds We don't freeze over here in Phoenix (typically, that is), so we tend to experience a big algae bloom in the Winter. We just had a caller this week tell us that we must be wrong about this because she had always heard that algae was more of a problem in the hot weather. She is not wrong, and neither are we. What’s the deal then? Our ponding system relies on a healthy ecosystem full of micro organisms and zoo plankton to keep the water healthy and clear. In a healthy ecosystem pond, zoo plankton are very active and do a great job in the warm weather, but they hibernate in the colder water temps. How much will YOU get? Well, that goes back to that ponds are individuals thing. Using copious amounts of beneficial bacteria in the winter is a waste of money. It does nothing to combat the algae. Beneficial bacteria is for cloudy water, not algae blooms. You can use other water treatment products, but take care to use them during the day, and never in the later afternoon or evening, because they steal oxygen from the water at night, which could kill your fish. The algae can also be hand-weeded out, and even used in composting operations or as mulch around plants because it's full of nutrients. But remember: aquatic life likes a little algae to snuggle up in during the winter. Plants in a Winter PondDO NOT thin or trim back your aquatic plants too severely just yet. In Phoenix, we technically have a chance of frost through the end of February. Many years, that seems practically impossible, but we've been surprised from time to time, so better safe than sorry. Annual CleaningsYour annual cleaning should be done when the water is COLD. So, plan to do that before the end of March. We provide that service, or you can certainly do it yourself. Before you know it (and for those of us getting older, it seems to be in the blink of an eye), the water will begin to warm, your fish will become more active, and your aquatic plants will burst forth with new life. Then, we can all start complaining about the heat again... Comments are closed.
