Hi splashpad,

With Palintest 25 pro+ Palintest I can test free chlorine, total chlorine, pH, alkalinity, calcium hardness, cyanuric acid, copper and phosphate.
Yep I'm aware of low chlorine level at the moment, generator is off after initial ScaleTec dose. (may help with calcium carbonate?) I will add some liquid chlorine later today.
I clean the filter a minimum of 7 days after cyanuric acid is added (to the skimmer box basket) Cyanuric acid is getting into the pool water (see recent results pool 2 forum share)
The pool definitely got SLAMMED!

Hello,
I tested NH3 again (6/3/19) and again it was less than 0.5ppm.
ScaleTec may have done the trick. I'll update in about a week.

Hi all,
ScaleTec has solved the calcium carbonate precipitate problem.
Still can't keep cyanuric acid levels up.
I'm going to hit it with ClO2 next.

Hi splashpad,
Thanks for the reply.
Time is the essence, the priests do say...
No. And it would be good to find a solution.
I'll keep persevering.

Hi James,

Yes. I've added 1 tab in the recent past (0.5ppm equivalent) on the suggestion / recommendation of the local pool shop.
C-5 tablets.
Now waiting for more tabs.
