I'm in the middle of a SLAM and I'm almost out of reagent! I have more ordered, but it won't get here until Friday. I estimate that I have 3-4 tests left. I was thinking of reducing testing to morning and night while continuing to add about same amount of chlorine as I have been until I get the refill. What are your thoughts on this or do you have any other suggestions? I'm already using the 10 ml sample to conserve.
