3 wks ago, after telling us our TDS level was high, we emptied, refilled, and added 30 dollars of chemicals according to what they said the pool needed. Today they told me the TDS level was high and to do another drain and fill. My God...I cannot afford all this water. Every other chemical was right on, other than the fact that the chlorine was sky high. I have a 14,500 gallon pool and keep 2-3 hockey pucks of chlorine in the floater. Pool good and clear. There are these new pockets of white granules forming clumps in several areas around the perimeter of the pool, which is concrete. Are these due to high TDS levels? Ours tested 2300 and the norm is under 2400. The one pool store guy said NEVER add liquid chlorine and only the powder. I'd rather actually b/c we are tired of hauling the gallon containers anyway.
