I've had the pool for about a month, so still fairly new at this. Have been following the Pool Math calculator and it has been working well at maintaining all the levels.
Over the last few days however, the FC level is stuck between 2 and 3, whenever i test it. All other levels are correct. Here's the data from this morning:
FC: 2.5 (added 39oz of 8.25% bleach evening before last, so was expecting this to be at least 4)
CH: 200 (have been adding Cal Chl the last 2 evenings, since this was at 160)
Any ideas on why the FC level is not rising? Pool is crystal clear, no algae or anything.
I have an in-line chlorinator that i put 3-4 tabs into per week, and then supplement it with bleach as needed.
