: Dear Members,
: As i like to know the How much Caustic soda flakes were to be added in one tonne of water to get the total solution 300 PPM Caustic Alkalanity.
: And also how much Trisodium Phosphate is to be added ne tonne of water to get the 30 PPM phosphate .

If you wish to clean a new system use 1lb of tsp per 50 gallons of boiler water capacity, warm to 160 and allow to run for 24 hours. Best to test for caustic using titrating test...to many variables can change the result of adding flakes.
