Large Calcium Pieces
I have recently discovered calcium pieces. They are dime and nickel sized flat pieces on the floor of the pool at each return. Recently, I added citric acid to remove some stains and the pH dropped significantly. I noticed the calcium after that. I vacuumed them up, rinsed the filter cartridge, and now 1 week later have noticed the chunks again.
I have never noticed significant calcium buildup on the SWG cell nor have I seen any deposits on the small electric heater elemements (same type of elements used in a hot water heater).
According to my numbers, I should not have any buildup, but I do have high Calcium Hardness. Not sure why that is going up because I am not filling the pool with city water, it is being filled by rain the past couple months.
Numbers as of tonight:
CL = 12 (a bit high I know)
pH = 7.6
TA = 100 (also a little high)
CH = 570
CYA = 70
Slat = 3500
Borates = 50
Temp = 90 F
Any suggestions? I plan to drop TA to 80 and drop the pool level if expecting a large rain to help lower CH.
