Operating & Cleaning a DE filter

[packerfan]

i agree with you for the most part and after reading it i say to myself why did i switch to DE. After having several sand filters over the course of 16 yrs, i couldn't stop sand from appearing in my pool, no matter what i did. new filters,different sand,etc. so i got frustrated and changed. i didn't know this DE would require so much work when opening my pool though. oh well got it now so will use it.

My Hayward EC-65 Perflex manual recommends soaking the nest in 20% strength muriatic acid blended with water 1:1. So why does Waste mention 10:1?

Dunno.

Either will work. BUT, most DE filters do NOT need acid. Acid removes calcium scale, which is somewhat rare. TSP removes body oils, etc, which is universal

ALWAYS, do TSP first. Acid reportedly 'sets' grease, creating irremovable goo.
