What are the typical signs of poor water circulation in a pool?

Cloudy water and algae growth are indeed clear indicators of poor water circulation in a pool. When a pool's circulation system is not functioning optimally, it can result in stagnation and inadequate filtration. This leads to the accumulation of debris and contaminants, which causes the water to become cloudy.

Furthermore, algae thrive in still water conditions where nutrients and light can be abundant. Without proper circulation, chlorine and other sanitizers may not be evenly distributed throughout the pool, allowing algae spores to multiply and take hold. A properly circulating pool helps to maintain water clarity and prevent algae growth by ensuring that chemicals are evenly mixed and that water is consistently filtered to remove impurities.

The presence of cloudy water and algae is a clear sign that the water is not circulating effectively, and corrective measures would need to be taken to restore proper circulation and maintain water quality.
