Still new to this method so am curious about why my FC would drop so drastically as up until this morning it was maintaining FC and would only need to move it about .5 to 1 ppm per day. But not today.
There are a few factors that have changed:
1. I was increasing the hardness of the pool by 25 ppm by adding 3.5kg of Calcium Chloride
2. It rained over night
reading from yesterday were
I did raise the CH to between 125 and 150 overnight.
I have added bleach to raise the FC back to 3.5. Just wondering if what I experienced is normal?
