I am installing a new 24 inch sand filter this week. (AG 24ft round pool, 1HP pump). Looks like 300 pounds of sand.. or 225 sand and 75 lbs of pea gravel. Still undecided about using the pea gravel, but I do have a question.
When do you add the pea gravel? When laterals are down in the tank? After reading so much about how fragile the laterals can be.. seems that pouring pea gravel over them, from the top of the tank.. could cause damage. Am I missing something here? Thanks for the advice.
