Hello! I have a public pool (About 600 users per day) with 6 Pentair Triton II Side mount filters. They are about 3 years old and get backwashed every 48 hours, sometimes every day. I read the manual and it says something about a chemical cleaning procedure. Is it necessary to change the sand in the filters or should I just do a chemical cleaning procedure?
