We bought a house that came with an 27' AG pool. It has a Pentair Meteor sand filter but I am not certain which size it is or how much sand it needs. The label on the filter shows that it is either 18", 20", or 22" but the label indicating the size was not punched out.
I do know that the 18" takes 65# of #20 silica, the 20" takes 100#, and the 22" takes 150# of sand. After adding 100#, the sand fills the sphere exactly half full. Should the level be higher than this or am I good?
I have been reading on TFP for a while now and bought the TF100 test kit and can't wait to open the pool and start putting the BBB method to work. Thanks for such a great site!!
