Well after 5 years of baquacil and people not liking the taste, and, having run out of baq chemicals I figured this is the year. My pool is approx. 8000 gallon above ground type with a dome cover and a 20'x4' solar heater. I've added approx. 250ml of chlorine and the water turned greenish in color. Last year fall I purchased a Taylor K-2006 kit (complete FAS-DPD Chlorine) anticipating the change over. After an hour with a magnifying glass trying to make sense of the manual I took a sample and attempted to do a proper FC test. I took a pool sample about 18" down and filled the large tube to 10ml. I dropped 2 dippers of R-0870 in an it turned light pink after swirling. Does anyone know why it says to use 2 dippers for both the 10ml AND the 25ml; seems like you'd use more for the 25ml sample?). And, right after that is says if the pink disappears to add more of R-0870 until the color turns pink (doesn't seem like an accurate method but I'm a noob).
Ok, so next I add the drops of R-0871 and it only takes 2 drops before the pink goes to clear, which supposedly is 1ppm of Free Chlorine, right? And I need this to be at 15ppm? That'd be a lot of drops, especially if I'm testing this water frequently. I'm afraid this expensive testing kit won't even have enough liquid to finish the conversion. Do the pool stores sell extra bottles?
So, then I add in the 5 drops of R-0003 and it turns very very pink. After dropping 13 drops of R-0871 and not seeing much of a change from pink to clear I begin wondering if I'm doing this right, and, if how much of the R-0871 is left in the bottle so I stop since I'm not even sure as we care about the combined chlorine at this point, do I?
I only bought 2 of the 189oz bottles of bleach. About how much should I buy to complete this for a 8000gal pool?
Thanks in advance for any insight on what I may or may not be doing right on the testing. Btw - I used a natural lamp for illumination as was recommended by the manual since it was dark out.
