In the directions that came with my kit it states to add 20 drops of R-0010 and then 5 drops of R-0011L and the mixture will turn red if Calcium is present. I'm using a speedstir so I know it's not a mixing issue per say but my intial results continue to come out pinkish with a purple tint. I've tried doing the test with the assumption that copper is present but again it starts out a "pinkish purple" color and not red.
So on to the question am I still looking for blue in the end? Or am I looking for any color change at all? If it's any color change, when do I stop? When the color has changed completely? Or as soon as the change starts? Sorry to be such a newb but it appears to be an issue for me as I seem to get some change in color at 40 drops (not blue) and then another change around 140 drops (again not blue). I'm trying to figure out where exactly my CH is as I have a ton of metals and sky high TA (>600) in my fill water. Getting a more accurate CH reading would allow me to use the CSI from the pool calculator a bit more accuratly so I know when it is safe to start my SWG up.
