Can you swim in a pool while the filter is running?

This is more personal preference than anything. It is recommended that the pump be on all the time, but usually only running it a couple hours a day will usually circulate the water enough. You want to run it to circulate the chemicals and to keep the surface clean from debree. Good luck.

I could not disagree more ---- Running the filter while swimming makes more sense since you want to remove the contaminants that you add to the pool from your body and from what you track in on your feet. Running the filter for several hours after swimming is also recommended. It should take from 6 to 8 hrs per day to turn the whole body of water over thru the filter depending upon your pump. Two or a "couple" of hrs. per day is totally inefficient. What that minimum turn over rate does is leave what the filter could not filter out that day and leave it for the next day -- to contaminate what already has been filtered clean - compounding the problem. Thus you never quite get a grasp on truly clean, clear, sanitized, filtered water. Having partially contaminated water increases the use of chlorine, algaecide, and other harsh products.

This above applies to gray or cloudy or green water or all combined. Good filtration and proper water chemistry are the key factors in good pool health -- for the water -- for your health. Having cloudy or gray water can and will be harmful to your health. There are several pathogens, parasites etc in this type of water -- Cryptosporidium - a parasite - which cannot be seen -- causes diarrhea. Other microbes can make you very ill. People especially females are susceptible to many of these disease causing parasites.
