It's more reddish to maroon in colour. The pH from the profilux sensor is 7.9. It was calibrated a month ago. My pH has barely every went above 8.0 pH.
It doesn't get stringy or bubble up at night. I think I will replace my GFO with some new stuff. Get my GAC and ozone running full torque. Siphon out what's on the surface.
Any other suggestions?
