I will be trying the BBB method (currently using trichlor pucks) and want to know if I should remove my solar coverfrom my AGP , as opposed to just rolling it back a bit, before adding bleach in front of the return. If I do, how long should I keep it off before putting it back on? My goal is to keep the new solar cover at least a full 2 seasons. My first cover started shedding all of its bubbles during the middle of the 2nd season and was shredding by the end. Thanks.
