Totally sick of cloudy pool with pollen, and yeah I'm sure it's pollen. Well aware of what folks here think of floc and I'm not interested in vac'ing that much water to waste anyhow. Question is, is it alright to add some DE through the skimmer with the basket out rather than havin to open up the sand filter to add it? 12k pool with 250 lb. filter. How much to add? Thanks!
