What are your thoughts about adding pea gravel first to cover the laterals and the rest sand. I have not been able to determine if one way gravel/sand or sand alone is superior to the other. Gravel supposedly protects the laterals and keeps sand from
plugging up or damaging them? Due to getting a fair amount of sand in pool from pump I am changing the sand and laterals and don’t know if I should go sand alone or
put down a base of gravel first? Please advise. Thanks Al
