Decide the calcium hardness by titration sodium hydroxide resolution is added to the pattern to take care of pH & then murexide indicator is added. Sample shade turns into pink & titrate the sample towards EDTA resolution this time sample color will change from pink to purple. This is the end point of calcium hardness test.
Temporary hardness – additionally referred to as ‘Carbonate hardness’. This kind of hardness refers to the calcium and magnesium carbonates and bicarbonates in the water. Heating the water or reacting it with lime removes this hardness. CO2 is launched as fuel and precipitates of insoluble calcium carbonate and/or magnesium hydroxide are formed.

These submersible UV Filter mixtures require no extra plumbing and in the restricted/ contained atmosphere of a reservoir, these are more than sufficient for stage one sterilization since the water turnover is likely fairly excessive (similar to a 30 gallon Rubbermaid type plastic trash can that I’ve used for this objective).
