25 ml= 5 drops/FC
10 ml= 2 drops/FC
05 ml= 1 drops/FC
More accuracy and precision higher on the list, less accuracy and precision lower on the list. (And obviously less Reagent lower on the list)
So the short answer is yes.
Also good to know! Thx! Although, ironically, the last time I did a backwash and refill is when I passed the OCLT with a .5ppm FC loss. lol
While I was backwashing and the returns weren't churning up the pool surface I took a pic as it looked so nice and clear...
I dropped a good 2" of water out and re-filled up with 3". Slowly but surely I'll get rid of that extra CYA.
