Solved.
5 Factors of Water Balance - correct answer ✅pH, Total Alkalinity, Calcium Hardness, Temperature, and total dissolved liquids Corrosive water - correct answer ✅pH is too low, dissolves everything it contacts scaling water - correct answer ✅pH it too high, mineral deposits on walls or pipes Regulated pH range - correct answer ✅7.2-7. pH reading is tested with Phenol Red To lower pH, - correct answer ✅add muriatic acid To raise the pH, - correct answer ✅add sodium carbonate (Soda Ash)
- sodium bisulfate
- carbon dioxide
Solved.
Total Alkalinity - correct 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 pH Bounce - correct answer ✅low alkalinity Regulated Total Alkalinity range - correct answer ✅60-180 ppm ideal goal is 100ppm To lower Total Alkalinity, - correct answer ✅add muriatic acid To raise Total Alkalinity, - correct answer ✅add Baking Soda Calcium Hardness - correct answer ✅amount of calcium and magnesium in the water (mineral content in water) Regulated calcium hardness range - correct answer ✅150-400ppm To raise Calcium Hardness, - correct answer ✅add calcium chloride
Solved.
