Okay, filter has been running about 1 1/2 hours.
Here's what I have:
So, what do I address first? Last year, upon opening, our CYA was in the 40s but now it is well below 20 (may even be 0). The dot never disappeared. I noticed the recommended range is 30-50 and I seem well below it. Not sure why.
Our TA and pH is low as well.
Any suggestions? Do I go ahead and at least add some chlorine to begin, at least according to the chlorine/CYA chart of 20 CYA or should I wait until later and check numbers again? Thinking maybe the filter has not ran enough yet.
