Does this mean that pool was not sealed properly by the spa (the pool is less than 2 yrs old)?

Thank you!

Allen, Thank you for explaining its Efflorescence, and I will keep my FC at 13 unless you suggest I stay higher. Yes, I am done with tablets. Since CYA is so high, I believe my TA reading may not be accurate. I will also turn on the aqua accent water features to aerate the water to help...

I have a calcium buildup around the negative edge spa. A wire brush did not work. My plan is to drain the pool a few feet and try CLR. Calcium crystals only show up in spa. Any suggestions about how to best treat this? Also I have been mostly using TFP protocols and recommended test kits for a...

What brand of calcium hardness increased do you suggest? Also after adding 3 gallons of bleach 12.5% last night my chorline 0 today! Any suggestions?

Oops you are totally right. I was testing at night! My Cya reading is 30 but I can still see dot. Is this a time I should use chorline tabs to intentionally raise Cya? Or is it ok that Cya is under 30? For calcium hardness the bag of chorlox hardener suggests ca of 175-225 but tfp app suggests...

I haven’t tested chemicals since de got in pool because we have people coming over for Labor Day and I’m racing around to get things ready.

Hard question. How will 1-1.5 pounds DE in the pool impact pool chemistry of 10k pool? Pool is a little cloudy from de but otherwise zero algae. I’m running cleaner and pool filter and now de filter is recharged.
