As temperatures warm, be sure to check your horses’ water daily, cleaning buckets, troughs, and basins as needed to keep the water clear. Vinegar and baking soda are safe and excellent cleaners; a handful of hay or straw—or a long-handled brush for tanks—makes the job easier. The hotter the weather, the faster algae will build up. If algae growth is a persistent problem, a diluted-bleach rinse will help curb it. Clean water encourages your horses to drink—a health benefit—plus discourages disease-carrying mosquitos from laying eggs in the water.
