HELP!!!! IVE BEEN DEALING WITH THIS FOR 3 WEEKS NOW.. THIS IS MY 2ND YEAR WITH MY POOL LAST YEAR MY POOL NEVER HAD THIS ISSUE. I HAD MY WATER TESTED YESTERDAY AT LESILIE'S POOL. IVE TRIED EVERYTHING. I HAVE A ROBOT VACUUM, A POOL BLASTER, A SKIMMER.. YOU NAME IT I HAVE IT. WHEN I TRY TO VACCUM ALL IT DOES IS BLOW AROUND THE Crud ON THE BOTTOM, MAKES THE WATER CLOUDY AND THEN NOTHING COMES IN THE VACCUM OR THE ROBOT. SO WHAT THE HECK IS THIS STUFF? DURING SWIMMING YOU CANT SEE IT, ONCE THE POOL IS SETTLED AND OVERNIGHT I WAKE UP TO THIS ALL OVER AGAIN AND ITS IN SPOTS AND SCATTERED AT THE BOTTOM. IM FRUSTRATED. IVE ASKED AND TRIED TO GET ANSWERS. IM WANTING TO EMPTY THE POOL AND STAY FORGET IT. CAN ANYONE HELP ME PLEASE. VERY ANNOYING.

Hi Princess!

Sorry you haven't received a response yet. Without a full set of reliable test results, getting to the source of the problem will be a challenge. TFP promotes pool owner testing and we don't trust pool store results. First step is to get a TFP recommended test kit ordered (Test Kits Compared), then download PoolMath. The app will help you calculate how much liquid chlorine to add to raise FC by 5ppm. You should do this each day until your test kit arrives. Post results when you have your kit in hand and we can help you out.

Check out Pool School and the Wiki page. Here a few articles to get you started.
