If you have this test, can you please measure volume of large bottle and distance from bottom of small tube to 30 mark
Just mixed water in tube with 12ml water and still able to see dot. Water level in tube exactly 3 inches. Looks like CYA is low.
First store test shows 17ppm, I bought 1.8kg of stabilizer and add, it should add 15ppm to my pool. week later store test show 15ppm of cya, I know its not accurate.
I SLAM my water during 2 weeks and keep 10-30ppm chlorine and it does not help. My tablets expire in 2019. Any way I can have high CYA level?
Trying ph level 7 and 40ppm chlorine
Now it 20 and 7.6
Calcium 150
Alcalinity depends from ph, when ph 7, alkalinity 120, when 7.6 - 180
Adding only muriatic acid and liquid chlorine.
New filter, working 72 hours now, before this old filter looks like not working.
