Things to Look for When Buying Horse Water Troughs
Before you buy a water trough for your horses, there are a few things you need to take into consideration. You should consider factors such as size, style, and material. In addition, if you live in a cold climate, you will want to consider getting a water heater to prevent the trough from freezing over.
Size: Water troughs can come in several different sizes. If you have a large pasture with several horses in it, you will want a large trough, such as one that can hold 100-150 gallons. For a small pasture with only 1-2 horses, something like an 18-gallon trough is more appropriate.
Style: Most troughs are oval in shape and are designed to be placed on the ground. Others are designed to be mounted on fences.
Material: Troughs should be made out of a durable material such as rubber or plastic in order to withstand the elements.
Heaters: Heaters can be a beneficial addition to troughs in winter. They keep the water from freezing over, so horses can continue to drink from the trough. If you have cold winters where you live, water heaters can save you the pain of having to break ice.
How Do You Clean a Horse Water Trough?
It is important to regularly clean horse water troughs to give your horses access to fresh, clean water. To clean the trough, you will want to dump out all the water and use a sturdy hard wire brush to scrub it.
After scrubbing, add a solution that is one part bleach and nine parts water. The bleach will kill off any bacteria or algae that has built up. After cleaning it with the bleach water solution, rinse the trough two times. Then, wait at least an hour before filling it with water.
Why Do They Put Goldfish in Horse Troughs?
People keep goldfish in horse water troughs to eat algae and mosquito larvae. However, in order to keep goldfish in your fish tank, you must have the right environment.
Since goldfish can grow large in size, you should keep no more than two in a trough, that is 55 gallons. They need the temperature to at least 60° Fahrenheit in order to survive. They should only be fed a small amount, if any, fish food in order to encourage them to eat algae and larvae.
How Often Should You Clean a Horse Water Trough?
You should clean horse water troughs on a regular basis to ensure the water is fresh and safe. Ideally, in the summertime, when there are algae and bugs to worry about, you should clean the trough once a week.
To help prevent algae growth, set the trough in a shady area. In fall and winter, you should still clean your trough, but it doesn’t necessarily have to be every week. In colder months, it is best to try to clean it 1-2 times a month when possible.
