Wow... I appreciate that insight. Didn't realize that the sand shouldn't be an issue. I do indeed know the spring pollen and it does build up thick. Never heard of a skimmer sock. Pardon my ignorance but what is DE?

I still have to invest another 300 plus for a pump. and with pump and filter at 500 it sounds tempting. But I am now thinking about another hayward, DE and a sock

Thanks again
