Sodium Bicarbonate & Calcium Hardness Increaser Timing

[FlapjackMcCoy]

Hello,

I was reading up on some stuff and realized today that I should not be adding Sodium Bicarbonate & Calcium Hardness Increaser at the same time as it causes cloudiness. However I could not find any guidelines on how long I should wait between adding them, and if I can wait less by the order I add them in - if one dissolves faster than the other. Any advice is appreciated.

Thanks

I would wait 24 hours. Both mix in pretty rapidly but you want the system to balance throughout the water column or cloudiness will result.

You have a fiberglass pool. Any reason you are adding calcium?

I assume your TA is below 50 ppm if you are adding baking soda.

Thanks, I'll add the calcium tomorrow around the same time I added the baking soda today. This explains a lot from last season, wondering why it was cloudy sometimes.

As per the shell manufacturer, on the warranty it says TA 80-120, CH 250-350. Today I used my TF-100 and got TA @ 80 and CH @ 200 which is pretty typical, I'll adjust those up a bit and in a few weeks when I test again 99% of the time I need to adjust them up again.
