I’ve tested via liquid my CYA and have never seen anything below 100. I so wish there was a more definitive test like counting drops. I’ve also tested using two different strips and they both come back 50. I tested the strips with tap water and they correctly showed “0”.
Which should I trust? Makes a huge difference in my FC target range. Thanks for your thoughts.
