How often should you clean the sand in your filter? What products should be used to clean the sand in your filter if you are using the BBB method?
I closed my pool today and noticed when I drained the filter that the water coming out was lime green. I backwashed thoroughly before closing and shocked the pool earlier this week and kept the FC levels up for a few days to make sure that all the algae was gone, so I'm not sure why I had all the green water in the filter. The sand was changed last year mid season.
Any input is appreciated.
