I'm pretty new to TFP and I think I'm starting to pick it up, but I was hoping to get some confirmation on some of my assumptions.
First things first, my water looks beautiful.
My test results (using TF-100)
PH - 7.5
CC - 0.5
TA - 100
CH - 300
CYA - 50
Borates - 30
According to the chlorine/cya chart my FC min is 4 and my target is 6.
I'm struggling with FC levels. I'm assuming I don't want my FC to drop below 6 (target level). I've been adding bleach to get up to 10-10.5 every night, but I'm dropping down to 5-5.5 by the end of the day. I'm not sure if I should be worried or not because I am dropping a little below the target, but staying above the min.
I know I have a couple things working against me:
bather load = 4 kids, wife and me, plus 2 golden retrievers (and sometimes the neighbors as well)
sun = South Texas (I do get some shade, but it's been extremely hot and sunny lately)
One of my dogs has a really bad habit of getting wet and then rolling in the mud before going for another swim, so I'm sure that isn't helping either.
Right now I'm adding a full jug of bleach every night to replenish the ~5 FC of chlorine lost each day. This feels a little excessive to me, but maybe my expectations are off.
Should I just get used to adding a jug or more of bleach every day? Do I need to raise my FC levels a little bit to make sure I don't go below 6 each night, or would I just be wasting bleach?
