A farm pond might turn red during hot dry weather due to a phenomenon known as red tide, which is caused by an overgrowth of red algae. These algae thrive in warm, nutrient-rich environments and can discolor the water in ponds, lakes, and oceans. The heat and lack of rain in hot dry weather can create ideal conditions for red tide to develop.
Generally you should remove the majority of green or red algae in a pond, for it could cause some serious problems. But if you have any algae eating fish (such as catfish), then the pond may be okay
