I have a hayward de filter. Its never been acid washed, and I found out recently that I have been not adding enough DE to it.
How would I go about cleaning it? I have heard soaking it in TSP or a degreaser for a week or two or more Letting fingers soak in a big bucket of water and degreaser.)
Do I need to acid wash it after that? Hopefully I didnt ruin it by not adding enough DE.
PSI never gotten above 20.
Does this info sound correct? What degreaser would you guys and gals reccomend?
