5 Factors of Water Balance
ANSWER
pH, Total Alkalinity, Calcium Hardness, Temperature, and total dissolved liquids
1
, Corrosive water
ANSWER
pH is too low, dissolves everything it contacts
scaling water
ANSWER
pH it too high, mineral deposits on walls or pipes
Regulated pH range
ANSWER
7.2-7.8
pH reading is tested with Phenol Red
To lower pH,
ANSWER
add muriatic acid
To raise the pH,
ANSWER
add sodium carbonate (Soda Ash)
2. sodium bisulfate
3. carbon dioxide
Total Alkalinity
ANSWER
represents the amount of carbonates, bicarbonates, and hydroxides in a solution - you want
this to be high, because the pH resists changes in fluctuating
