Since the finish of my pool build in November, Ive kept all my numbers within the rails pretty much, per all the good advice here. My CYA has been between 30 and 40 consistently, and my FC has been above 5. We've had a lot of cloudy weather, cool, just typical winter weather. Now we're getting into a run of nearly 80 degrees, sunny, and the days are getting longer (thank goodness!!). Now Im considering bumping my CYA level up to 50. Does this make sense? Or should I plan on something different.
