50 is a reasonable number. But you still don't know exactly what your CYA level is, do you? The lines get awfully close together, and it's a hard test anyway. What you see as 100 could well be 120 or 130. You might need to replace 75%. That's why Extended Test Kit Directions saysWhat's the goal for my CYA to be at? Pool calc told me to drain about half the pool. I'm just worried about draining that all at once. Which is why I was thinking to drain a little at a time.
Draining it in stages is not a bad idea, but the bigger the replacement each time, the faster it will go and the less wasted water. 10% of your pool will only be maybe 4 or 5 inches at a time.If your CYA level is 90 or higher, repeat the test adjusting the procedure as follows:
- Fill the mixing bottle to the lower mark with pool water.
- Continue filling the mixing bottle to the upper mark with tap water.
- Shake briefly to mix.
- Pour off half of the contents of the mixing bottle, so it is again filled to the lower mark.
- Continue the test normally from step 3, but multiply the final result by two.

These are diverters:Could I tell a diverter by looking in the skimmers?
Like would it look different?
On a Holiday Weekend at the start of Summer, I'd call it a steal.Hmm, definitely didn't notice anything like that. They left the number of the company who usually closes their pool. The guy said he could swing by tomorrow and take a look. Said max charge would be about $75. Same as you said he'd really need to See it in person. I'm thinking it's worth $75 to have someone figure this all out for me so I can label the cables and all. Do your think that's a decent deal?
Haha okay, see that's what I figured. So I'm just gonna have him come. See if he can figure it out.On a Holiday Weekend at the start of Summer, I'd call it a steal.
