Not sure what you just said about adjusting the reactor. I thought it was 25 drops=1ml(do you think the extra 10 drops would make a big difference). However: I just infused the receptor chamber again...3.7 grams of both CA & SC in 3 tsp of DW, No syringe yet so to test I used 25 drops of solution to 250 drops of DW= almost no change/ maybe just over the 100 shade. I am following directions on the test strips. So far this is 11.1 grams of material for a PPM of maybe 1000. Something is bad wrong somewhere.

After about a minute in the reactor chamber, the mixture of CA & SC is a dark brown color and after 5 min, with air pump set on low, the reactor mixture is a light pale yellow. All chambers are plastic water bottles. I did not wear the 3M mask and notice no overpowering smell.

This may be operator error...though not sure how.

Any ideas?

If you are trying to do a multiplication factor of 10 for the test strips I believe you should be doing 25 drops (1 ml) of solution in 225 drops (9 ml) of DW.

Certainly useable, you may want to adjust the doseage amount. Use 1.2mL to be the equivalent of 3 drops of mms.
