Your CYA is a little high. The recommended range is 60-80 for the Aquarite with 80 being the number to shoot for according to the aquarite manual. Also, according to the manual and using your test results your Saturation Index is low @ -0.45. The manual states that anything below -0.2 is corrosive and anything above 0.2 will lead to scaling and staining. Your Alk is a little high as well, range is 80-120. Hardness is low, range is 200-400.
