Salt Water Pool

[Naam]

It takes about 40 - 60K Baht and three hours for the conversion.

only? but does it take three hours to add 2.5 ounces of 24carat gold powder to the water?

All things considered I think for the Thai climate I would reocmmend a salt chlorinator. To around the lack of cyanuric availability the cell size could be increased.

For those on the economic fence, it is probably more expensive to run a salt pool when all costs are taken into account. However, given the time benefits and health benefit this is probably outweighed.

By the way salt chlorinators do not affect pH. NaCl + H2O does not a hydroxide make although it can, it also makes hydrogen which combines to form H2O again, so it is neutral.

As someone who has dealt with hundreds of salt water pools, my experience is some what different. The overall chemical equation is a little more complex that what you have posted there.

The process makes hydrogen gas as you aluded to above, the result is a OH ion floating, which is attracted to Na ion having been liberated from the Cl.

The reason for the recomended gas loop in the system is so if there is a fault and H2 is formed, it does not create a potentially explosive situation in the filter. In the early days there were some accidents of this type. Modern chlorinators also have a water flow detector that controls the operation of the chlorinator, ie no water flow no power to the chlorinator cell.

This is not the place for this discussion, however, try writing the equations out a few different ways you will be surprised. Salt water chlorination is not as simple as the pool industry wants you to believe.

Has any body got a salt water pool? if so can they advice of anybody who can "install\convert" a pool.

Thanks

I used P&N Pool Shop Co. LTD. A retired expat owns the company. I believe he only works in the Patttay, Chonburi area though. He can build or convert a pool to a saltwater pool. It takes about 40 - 60K Baht and three hours for the conversion. You will save endless amounts of time and money. I always have neighbors asking about mine.

Mister Pool in Bangkok installed my salt water chlorinator. They recommended the manual cleaning version if you use a maintenance service - the self cleaning model still needs its plates cleaned about every 6 months anyway and costs about double. I paid only Baht 22,000 for a 100cu metre pool (12x5m) and I am very happy with it. The pool now has a very slightly salty feel and no more reek of chlorine. It is better for human skin and also for dogs like golden retreiveers who can't resist water but get terrible skin disorders from chlorine. I had to get rid of the previous maintenance company because they didn't have a clue how to work with a salt water chlorinator, despite their protests to the contrary. I switched to Mister Pool for maintenance and they do a good job and maintenance cost including salt is 20-25% less than previous cost with chemicals. I also don't need to store dangerous chlorine in my shed any more.

saline units simply release the chlorine from the salt (sodium chloride) you add to the pool. they work reasonably well, but you would probably have to shock treat with chlorine once in a while especially after a heavy rainstorm. the unit is simply a 12volt transformer and cheap bridge rectifier and you can build your own easily or simply buy yourself a 12volt bayttery charger. with a capacity of 5 amps and it helps if you get one with built in ampere meter since you can then guage whether you have to use more salt. the higher the amperage drawn the more salt there is in the system and the more chlorine will be released. i added salt(ordinary rock salt that they use in cattle farming and really cheap,) until the meter showed 3amps and it worked for me. i used a system like this in south africa in my home built pool for many years and it worked very well. the trick is finding the correct material for the electrodes-i just bought replacement electrodes for a well known make at a poolshop and used them. they are available as replacements since they eventually erode away and you should have no trouble sourcing them.the units available in south africa use a 4inch pvc tube open at one end with the electrodes mounted inside,and this is simply immersed in the pool.no hydrogen bombs or problems related to flow -simple and reliable and very very cheap to build. salt in the system will not damage your pool,pump or plumbing.

you can save a fortune in chlorine each month using this system.you can test this system by adding ordinary table salt to a glass of water-make a strong solution. split a penci;l in half and clamp a piece of pencil lead to each of your battery charger leads.immerse these two temporary electrodes into the salt water on opposite sides of the glass and in seconds you will smell the chlorine gas being released
