I'm just wondering how can my alk different by like 3.xx??
And ca is off by 100ppm? Wow feel like I just wasted $50
With the Alk becareful no bubbles and glass is clean. I usually wipe it down with cloth before I put it in on C1 and C2 etc. The only times I have gotten bad readings is when something is in the water and the lights sensor I guess gets confused.
