Hello Folks,
I'm new to TFP and am hoping someone could offer some insight into my situation.
I'm running with a cartridge filter in a 15,500 gallon above ground pool. A couple of weeks ago I found algae starting to grow in my pool that I, and the pool store, couldn't figure out how to cleanout. I found this forum and ordered the TF-100 test kit to find that the reason for my algae bloom was likely because my CYA was around 80, a bit too high for my FC level.
I calculated that it would take about 2 days to refill the pool half-way given that I was on a 2 hours on, 1 hour off schedule to try and not stress my well pump too much. Over the 2 days I still was scrubbing with the brush consistently thinking that with the new water my PPM CYA would go down and free up some of the bleach to do its work. Around 10:30 PM last night my pool became full.
Right after the pool became full I tested my CYA again and it still tested at 80. Being kind of confused I looked again and saw that I could still kind of see the dot and that perhaps it was only a CYA of 60. The dot is a little difficult to see because of the way my lighting refracts off of the water, but I'm hoping someone could offer some insight into water testing and filling a pool. At this time the pool pump wasn't even running yet so the water hadn't properly cycled, but I was still hoping for some results given the 50% water replacement. Which brings about the question: How long after turning the pump on should I test CYA again to get an accurate result?
Before leaving for work I gave the pool a good scrub down with the algae brush and assumed a CYA of 60, so I added enough bleach per your formulas to bring the FC up to 24.
