Alkalinity

Alkalinity Testing

Alkalinity is the capacity of water to neutralize an acid.

P = Phenolphthalien  & changes color @ pH 8.3

T = Total & uses an indicator that changes color @ pH 4.5

High total (T) alkalinity results in a higher chance of foaming and carryover

-

Hydrate alkalinity (OH  ) = 2P - T

-

IF results ≤ 0, then hydrate alkalinity = 0

Low hydrate alkalinity (OH  ) results in inability to chelate ("grab") Ca   and Mg    which may lead to scale formation

Bromine

Bromine Testing

Bromine, along with other halogens (such as chlorine and iodine), make excellent biocides by "biting" holes in exterior bacterial cell walls.  Bromine can then enter to disrupt and kill the organism.

'Free' Bromine refers to unreacted, available bromine.

Note:  Some test kits simply measure halogen concentration.  That is, the kit may say that it is measuring chlorine, but it also is measuring bromine in addition to any chlorine present.  Normally this is not an issue as that only one biocide is used at a time.  Please see your kit's manufacturer for further instructions.
