I am testing our water daily, and adding liquid chlorine, and our water has been crystal clear since opening in early May - this is the longest we have gone with such sparkling water - thank you for the education! We used the tablets in the past and paid the price with high cya (90+). Before re-opening this year, we drained part of the pool and are on track with a cya of 50, only to find that liquid chlorine is impossible to find in the stores now! I really don't want to go back to the tablets and undo the results we have achieved. I have 2 gallons left and have been using between 35oz - 53oz per day to compensate for the loss of approx 1.5 to 2.0ppm fc each day. I thought it would last longer, but from what I've read here, this amount of loss each day seems reasonable in sunlight. Any other suggestions on what to use? I've only got a couple of days left on hand. Suggestions appreciated!
