OK, so I'm confused again. Not unusual for me. I didn't know I needed to do a calcium test in a vinyl pool. The only other test in my kit test for hardness? Is that what you mean? It shows NO hardness. My TA has always been around 180 and that was even with the fill water the first time I filled the pool. I am giving a party for my brother on the 19th and would really like my water to be clear. This is my first REAL problem since I joined this forum. It is making me nuts. I did put a knee high panty hose over the skimmer basket yesterday as i have no sock. Anymore advice? PLEASE. Thanks, Gladys
