Todays numbers-

CL- 5-10
ph- 7.5
alk-220
cya-30

I have added ph minus for 4 days now and my ph and alk will not drop! I have had a ton of kids in there to help aerate too! Is this another long process? should I go buy alk minus from Walmart?

Please help! My water is back to being cloudy again!

Also my test kit says to test cya 2 times per summer--sound right?
