First Time Bullfrog Owner - Need help with Frog Ease System

[JamesW]

To maintain the silver at 25 ppb, or above, you need to keep the salinity at 40 ppm or below.

Do you have a K-1766 test kit to check the salinity?

Why will it test as CC?

I don't know why, but it does.

If you are using the Frog system, and you do a standard FAS/DPD test your CCs are going to show off the charts. It just does.

This is from the Smarchlor manual itself - https://www.kingtechnology.com/wp-c...manager-files/@ease-In-Line-System-Manual.pdf

"SmartChlor is self-regulating.However, if you use standard test strips, it may appear that total chlorine is higher than the free chlorine. No worries—the strip is measuring the SmartChlor reserve, which will shift to free chlorine as needed. Please always use the FROG @easeTest Strips that were included with your System."

So it appears that the "Smartchlor Reserve" shows up as CCs

Chlorine has an equilibrium with CYA and DMH.

Chlorine dissociates from the CYA during the FASDPD test, so it tests as free chlorine.

Maybe chlorine binds much more strongly to DMH than it binds to CYA?

It might require waiting for a few minutes for the Chlorine to unbond from the DMH.

+ FROG @ease System consists of the FROG minerals silver chloride and carbonate used with 0.5 ppm of FROG @ease SmartChlor Cartridge.

The FROG @ease Mineral Cartridge (EPA Reg. No.: 53735-11) must be used in conjunction with the FROG @ease SmartChlor Cartridge (EPA Reg. No. 53735-14).
