I've been slamming. Opened on the 24th to a green pool. My liquid chlorine purchased in April is weak. The brand that I have used for years with no problems has a good until date instead of a born on date. It says it is good until January 23, but it has a weak scent and barely lightened a blue cotton rag when I tested it for strength that way, also it barely registered on the drop test. So I've been slamming with 78% Cal Hypo. Grrrrrrr. I much prefer a good high strength liquid chlorine.
Passed the overnight test this morning after going through 25 pounds of Cal Hypo so surely the algae is dead. I know that sounds crazy, but the pool is large and the algae was eating it as fast as I could put it in for 2 days. The water is now a glowing light blue and very cloudy. Now I'm waiting for the chlorine level to come down to 3-5 ppm before adding CYA. I ran my slam on zero CYA at 10-12 ppm chlorine.
I hope to get back to liquid chlorine but I cant justify paying $4 plus per gallon as I have to use at least a gallon every day to maintain 3-5 ppm. I've always paid $1.99 per gallon which was reasonable but with these price hikes it is difficult. If I can't trust the potency, it becomes a no go. Even the Cal Hypo in the 25 and 50 pound bucket is much more expensive this year. I am also paying double for CYA. Grrrrrrr. It's all worth it, of course, but I must grumble.
I will be back washing the sand filter later today and hoping this cloudy water clears up after that.
It's windy here today and my pool water is 65*. Yikes!
