Hello! Yet again we closed inappropriately so now we pay the price! Trying to get pool opened and started slamming Monday! Still at it ... Problem was I was out of CYA reagent so I was keeping FC at 20 as a best guess...got the reagent yesterday and results are nil! I've tested twice to be sure and the mixture is completely clear! So assuming this is accurate and I have none...is this going to make slamming easier or more difficult?? And as frequently as we are back washing, I'm not seeing how I could add any stabilizer at this point. Any help would be appreciated.
Results at first test this am:
