    Triton II filters sand change or chemical cleaning?

    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?

    Thanks for all the help!

    You should never need to change the filter sand, unless you let the chemistry get WAY our of whack and calcium scale develops.

    It is a good idea to inspect it and do a sand cleaning every year or so. See this post:

    With that much use, I would certainly open the filter and inspect it at least yearly, if not twice each swim season. That swimmer load is w-a-a-ay more than residential people deal with and you need to look inside and see what's going on, if anything.
