Opened pool, tested CYA with it possibly being under 30

[summertimesadness]

Opened the pool for the summer and first thing I tested was the CYA for SLAM.

As this test is my least favorite, I did it multiple times and it trended towards Barley being able to see it past the 30 mark in the tube. (The solution was just at the top of the tube)

I added 1 gallon of LC to get started, brushed the pool and called it a day. What is the recommendation for the CYA so I can get started for SLAM. (I know i have to be at a minimum of 30)

To mix it for 24 hours before you trust it. It takes the same time to re-disperse as it does to disperse the first time.

Then if its under 30, make a judgements call if you should add 10 / 15 / 20 because you likely have some, its just a question of how much.

Welcome back.

The test is the least objective but also the most forgiving. So if your test says 30 but it's really 20 there will be no harm.......just read it the best you can and assume your reading is correct.
