Skimmer Socks Warning
I have been using skimmer socks for a few years and it does seem like it's a sand filter saver. Only backwash three times or so per year and the water comes out very clean. But what I have realized this year opening the pool, as I stirred up the algae from the pool walls and floor, and poured in liquid chlorine, I noticed these socks filled up quickly with dead algae and quickly plugged up the skimmer to the point I could not remove the skimmer without shutting off the pump.
Just a warning to be very careful because I am sure you can burn out your pump in no time due to the fact that it's struggling to suck in water from the pool.
Literally used for socks and a 3-hour period.
I wanted to run the filter through the night so I had to reluctantly not use a sock in the skimmer basket.
