TA too low @ 50ppm?

[Titan7]

Ran to tests today
FC was 10ppm
TA was at 50
PH was 7.8
CH was 650
Salt 2800
cYA 65
Csi -0.03
Temp 59

Just never had TA go below 60-70, odd. FC is high as I adjusted the salt cell %.

i try to keep my ta at 50ppm
if your ph starts swinging wildly you will need to boost your ta
not sure how low you can go
if it hits 40 i would bring it up to 60

Check your CSI using Pool Math. If it is close to 0.0 then you are good to go. If it is not then you can play with the numbers to see what needs to be adjusted to make it close to 0.0. Know that the water temp plays a big part in the CSI

Here is some info on CSI:

"CSI Calcite Saturation Index - requires pH, TA, CH, CYA, Temp, uses Borate, Salt
Less than -0.6 is suggestive of problems for plaster, tile, stone, and pebble pools.
Greater than 0.6 is suggestive of problems for all pools."

Pool School - Calcium Scaling

I hope this helps.
