We use Alex with the medical strip reader AND individual titration as well.
Alex will read TC & FC to 10ppm
as for a chlorine demand in this salt pool a few things to note:
1. Pool Water Temperature: CG's dont work in temps below 55.
2. STOP USING LIQUID CHLORINE - you are not a commercial pool, Commercial pools MUST drain every year because of high TDS levels. Liquid Chlorine is unstable, 12% at the factory, hopefully its a fresh 9% by the
time you put it in your pool - therefore, 91% dissolved solids!
3. Clean the cell.
4. Try treating the demand with both Cal Hypo & Potassium Mono.
5. Or just leave it alone if the pool is crystal clear - set your cell to 80% and let it run 24/7, but clean it first
just a note:
Perhaps I am biased, but I have been in this industry since 1986 from building to chemistry. Many right answers, until you visit CDC and see all the accidents caused by "STRONGER" pool chemicals.
sorry to ramble, just feel the need to educate!!
