I am the owner of an great Artic Klondike and running it the tfp method with chlorine an hydrochloric acid. In one of the pipes I made a T-fitting where a ball valve (VDL PVC Kogelkraan 2 x binnendraad - PVCbuis) is attached to which a hose goes to a perstaltic pump (Slangenpomp MP2-R (01-03) -...

Hi, Using tfp in spa for now over 2 years and works like a charme. Using stenner like pump to inject liquid chlorine during filter cycle. I noticed suddenly that the poolpal app that i use for recording values is suddenly showing weird numerbs for CSI and LSI. With: Temp 102.2 F FC 5.5 CC 05 PH...

is Arm & Hammer Baking Soda the same as Natriumbicarbonaat Sodium bicarbonate, NaHCO3 the Arm and Hammer Baking Soda (Arm and Hammer Baking Soda 454gram, nu 7% korting) and it seems like the equivalent Natriumbicarbonaat / Sodium bicarbonate, NaHCO3 (Baking Soda (Natriumbicarbonaat /...

Triggered by a remark of chemgeek in post Foam that isn't? "By the way, don't forget to use Dichlor one day each month to help maintain the CYA level. You might test for the CYA level to be sure it's not too low. Chlorine slowly oxidizes CYA in hot tubs at the rate of roughly 5 ppm per month."...

Became a forum member and tried to see what testkits are available but site seems to be nowhere :( ?

Since a short while the owner of a arctic spa and in research of more information about how to balance the water i stumbled over TFP. I tried the teststrips, they don't really work. Very hard to determine the correct values. So i decided to purchase a liquid test kit and set my mind on a TF100...
