Convert one of those french pools

[PoolDoctor]

Nothing against the French of course, but if anyone wants to convert their pool (embedded equipment in the white box pool side) to a "real" pool, just give us a ring. We have done one pool today in Chantaburi. We removed the old equipment, and extended the piping (2" inlet, 2" outlet) 30m to the main house. We then bored thru the storage room floor, and extended the piping to this small room. We then installed a nice 2hp pump, 28" filter, salt water chlorinator with pH control (minus of course), control panel, valves, etc., beautiful job!

A common question we get is, "why do we need pH control" with an automated salt water chlorinator? 90% of all pool companies in Thailand will not be able to answer this question, nor give further advice.

Ans: the Ph of salt water pool tends to rise over time, and will eventually exceed 7.8 on the ph scale (the water is becoming more base). This is a natural phenomenon of salt water pool chemistry (related to the production of chlorine gas from sodium chloride). When pH is high, chlorine sanitation efficiency is low. This causes water that is not being sanitized completely. The 2 are inversely related. When pH is low, chlorine efficiency is high, however then you have to worry about the damages caused by acidic water. So then, to gain maximum chlorine efficiency without generating acidic water, keep the pH between 7.2-7.8. This will allow maximum chlorine efficiency, at minimal acidic damage. To keep the pH down into this range, ALL salt water generators should be coupled with an auto Ph injector. Or, manually dose the pool with muriatic acid from time to time.
