I read a thread about closing . It says to bring to shock level for 24 hours. After that should I wait for the fc ppm to drop to a certain level before covering ? And do you guys add algacide for the winter? Thanks in advance for any advice
No, not in the winter. Not sure too many owners actually bother after closing, although much probably depends on whether or not the owner can get access to the water after closing since some covers (if used) can be a bit more difficult to pull back. Getting the Poly to circulate would be the other consideration.Does Polyquat need to be added every 3 months also ?
