I feel your frustration. That's a pain. I don't have that same issue with the FC test, so I don't have any suggestions. I use one scoop on the 10 ml test as well. Sometimes there's a few particles left and sometimes not. I do one drop at a time by holding the tube in my right hand and swirling while doing the drops with my left, then slow down as the pink of the sample fades. I allow about 1 second per drop so the drop fully forms. Not suggesting, just describing in case it helps.
You can definitely swim at 12 FC with 30 CYA, so if you want to swim including the kids, add 10 ppm CYA and continue the SLAM at 12 ppm FC. Or before doing that even, test it yourself by swimming underwater with your eyes open for a while. Your pH has to be within 7.2 to 7.8, but I think we got that in range before the SLAM.
If you think your CC is 1.0 ppm, then that criteria is not met to call the SLAM done. But it's your pool and your call, knowing the method and what's happening, and that you don't want to do it again. The fundamental of TFPC is knowing what we're doing and why, and you've got it!
You can use the SWC any time you want, except if you're doing an OCLT and the SWC runs during the night. A reasonable starting point is 5 hours at 40% (2.9 ppm FC) for the Electrochlor 30.
Hi needset
I recall Caco telling me cc at 1 in sydney meets criteria due to the chloramines already existing in our tap water?
Also how did you get the spec on the electrochlor 30...the manual doesn't say much...also my lcd is the 30 but the actual cell is the 25 i believe...does it make a difference
