Chlorine vs Salt Pool

Postby brianks » Fri May 13, 2016 12:05 pm

[/attachment]My 4 x 14m salt pool is now 2 1/2 years old now and I have gone through a big learning curve (hell) for 6 months but appear to have everything under control as far as maintaining it properly. The one thing I do not like about my salt pool is having to deal with the HCL to bring down the Ph periodically. Transferring the HCL to smaller containers and adding it to the pool is an extremely dangerous process which requires the use of a big fan to ventilate the area to make sure you don't get overwhelmed by the fumes. Other than that, my chlorinator works well and with the PoolRx have had no problems keeping the chlorine levels acceptable even in this now 34 degree water temperature environment.

My neighbor has a new pool and he switched over from a salt to a straight chlorine pool because he did not like the salt residue on the decking around the pool. Since he has switched to a Chlorine pool there is no need to worry about the Ph as I monitor the pool for him and check the chemicals weekly. His blue tiles make his water temperature 1-1.5 degrees warmer than my white Bottom Pebble Tec pool. Keeping chlorine levels right and high enough requires two chlorine floaters and constant monitoring of the tablets. Overall his pool is much easier to maintain than my Salt pool (cost of chemicals not considered).

Because of my severe dislike and dangerous HCL I have been considering switching to a chlorine pool when my 7 bags of salt are used up probably after the next rainy season.

Was curious if any of you had any constructive comments on my situation.

Thanks very useful for someone about to embark on a pool

Keep us posted if you make the switch

i recommed Klondykes posts about water chemistry they havea lot of insight no pool shop will ever tell you.

Also bear in mind... that a Salt Pool is in fact a Salt Water Chlorinated Pool, so the Chlorine gets produced from Salt but in the end you have all the disadvantages or a Chlorine pool regarding health concerns.

I think its well worth to look into to other sanitazion options like Bionizer (Copper) and Ozone.. althoug those pricey machines are designed that you also need to spend lots on in replacement products to keep it running, therefore the Klondyke is actually better imho.

Dear Oil, many thanks for your recommendation. Will give aside some commission for you. :D

As of the HCL handling, better than to pour it pure directly into the pool: prepare a larger bucket full of water and pour carefully the HCL in that - over a small 2L bowl with handle (as used here for Abnaahm) to see how much you are giving. And that should be made in an open air. I suppose you have got a 30l gallon of dark blue or black pastics, bought at a chemical shop. Then, this larger bucket (10 - 15 l) with solution some 1 : 10, can be distributed around the pool, more easily than the pure HCL.

My 2 cents of the recommended water chemistry experience:
After studying many sources in the Internet, where the pool forums are mostly owned by the pool shops, I have found that their advices of the strong chlorination are very useful - for the shop owners. And after their valuable advices the most word count in their forums is; Help, green water, desperation. Pity the people who invested big money for the few sunny days in Europe...

The biggest problem with the water (especially in the hot countries) is green water by algaes. To avoid their growth you need (as per shop owners' advice) very strong chlorination that has to be kept on its strong level almost daily as it evaporate very fast. And to make the chlorine good effective you have to maintain the pH - almost daily. Both chlorine and the pH (mostly PH Minus) are the best selling articles. And the big daily headache for the pool keeper and his money wallet.

Moreover, the strong chorinated water is not very healthy for the swimming population, especially small kids. That can be also found on Internet with many studies by medicine experts who - unlike the shop owners - do not sell anything. :?

So, for fighting the algaes are more suitable (and made for that purpose) other means of many fashie names - algicids - most of them based on copper sulphate. So, you can handle the water directly by the CS that has the disadvantage (for the pool shops) - is very cheap. :evil: I am buying a 1 kg sack at a local chemical shop for 150 Baht, distributing into the pool every week (sometimes forget) a plastic ladle of it (some 100 g) quickly dissolved.

The arguments of pool shops against CS are not true, even the drinking water allows 2 ppm (2 mg on 1 l) of Cu, whilst CS containts only 20 - 25 % of Cu. Strongly used in many food, fruit industries, mainly wineyards.

Then, to be sure about the bacteria - the pool shops make such a big scare of - I dissolve a spoon of chlorine directly in pool twice in week (sometimes forget). That's enough, much better protection against any germs than you get on your door knob and/or outside at the Big C, market, school, train, etc.

For this low chlorination level I do not need to worry about the pH. And the pH does not have any influence on the water clarity. Nor on your health, the drinking water standars allow from 6.5 - 9.5. Perhaps for swimming not so good? :lol: The sea water is some 8.3, SPAs (the ones for health) even more.

So, with this my minimum care (and a simple pump/filter equipment) I get clean and clear water for my daily 1 km swim throughout the year. Even when I am getting my water from a strongly ironized source (entry in the next issue of Guiness Book of records :roll: ).
Picture as of today after strong rains that bring daily a lot of green dust from the spring blooming vegetation around.

Re: Manual Chlorine vs Salt Chlorination

Just a reminder for anyone who has been confused over the title of this thread:
A 'salt' pool generally uses a salt water chlorinator, a system that converts salt into chlorine by electrolysis.
Therefore the correct discussion would be:

pH: There is a very good alternative to handling hysdrochloric (Muriatic) acid: It's usually marketed as pHminus. It's slightly more expensive than neat HCL but easier to store and far less dangerous. Its a powder. Shop around because the prices differ greatly for the same product. The correct level of chlorine will only work when the pH is maintained beteween 7.2 and 7.6. There are no advantages in overchlorinating, except or the monthly shock chlorination. Persistent green algae should be addressed with an appropriate agicide specially prepared for pools. They are usually copper sulphate based, and like most pool products in Thailand, prices differ greatly for the same thing.

Automated chlorination systems, ionisers, UV, and ozone and systems often represent an important investment for many pool owners, although prices are now far more reasonable. When considering salt water chlorination, examine the market here in Thailand very carfully, there are currently only two brands that have a genuine customer and product support here, and that suppport is not offered by every retailer of those brands. A good salt water chlorinator should last for many years but the electrodes need replacing and you need to be sure thay will be available and not as in the case of the Poorite brand which went into liquidation leaving even no guarantee support for the Enduro and Surechlor models.
If you are having a pool built, be sure to ask your pool constructor what brand and model he intends to install (it may be old stock, and in some pool shops too). Also, very often the manufacturers' descriptions are often only advertised on performance in cool or temperate climates whereas pools in the tropics require a higher GpH output, and many pools builders may not be aware of this.

UV systems for pools have been introduced very recently at extremely interesting prices and which are now a viable alternative to chlorine and salt water chlorinators or ionisers, some of them are also equipped with additional ozone production at very little extra cost. After 10 years I have now replaced my saltwater system with one of these. The huge advantage is that it is less expensive to buy and requires no maintenance - no expensive electrodes or annodes to replace every few years (except the lamp which is not expensive), no need to stock salt.
