Yes Sfpat, it is just about like brushing your teeth every morning. The E10 does a good job with the ultra fine filter upgrade. A new Wall Whale brush has been a wrist saver.
My test readings from Friday:
FC 6.5
CC 0
pH 7.5
TA 90
CYA 50
I am a little unsure about the TA. My card from the test kit says TA should be 100-120. The chart of recommended levels here says 50-90+. Is there really that wide a range of acceptable levels? Or am I looking at something wrong? It had been at 100 since my first test. After several days of torrential rains and backwashing 2-4 inches, TA was at 50. I got it back to 90 with soda, but wonder now if I overdid it.
