Hi All,



Given the horrendous fresh water problems, I am interested in learning about saltwater swimming pools. Can anyone offer any advise and of course any shortcomings of such a system. Any comparison on installation and maintainance costs and schedules, would also be most helpful.



Thanks in anticipation,



wynyardman

Can't see any problem adding sea water to a chlorinated pool, so long as all other level kept correct (ph/Cl). In fact, on a 9x5 you wouldn't even taste it for the first 8 tons or so.

We have a chlorinator, and when water become a problem, I will just remove, insert a peice of dummy pipe, top up with sea water and add chlorine.

I know an enterprising water tanker chap who will understand the pool water situation, and I am sure be smart enough to realise if he provides sea water, and his number is put on the BB's he will do a good trade.

Hi Simbas,



I have had proposals from Esentepe Pools for such a system. I am just trying to get my head around the technical aspects. May be worth a call though.



contact Murat Bahadir 0533 8774093. He speaks excellent English.

Hi Brian24001,



Very interesting thank you. I would certainly suggest that your enterprising friend, puts forward proposals on this site.



Good thinking,

Nice one John,



I would be interested in this. Pool and Villa a little while from completion. Must be a hell of a lot cheaper and somewhere to keep the fish!



Simbas, let me know if you get your pool done etc, as we will be close neighbours.



Regards,



Tiggy

hi everyone,

how does salt water chlorinator work?

salt is added to the pool water,0.35%-0.4% salt content.

this slightly salinated water then passes through the electrolytic cell and this produces chlorine gas,which prevents algae and purifies the pool.

so the salt water pool is not sea water pool



advantages:

irritation to eyes and ears is eleminated

unpleasant taste and odour is greatly reduced

no more needs to store expencive and hazardous chlorine,

sparkling clear pool water



disadvantages:

your pump needs more running time

Hi Murat,



It seems that you are our technical advisor on this one!



Question....If the pool is initially filled with fresh water, can sea water be used for all top ups?



If so this shows promise.

we f not fill it up with sea water. we add salt in it.

Wyn,

To answer question, you could initially add seawater to a fresh water pool when a chlorinator is added until you acheive the required salinity, however, future top ups would then have to be fresh water.

Reason - chlorinators require a certain ppm of salt in solution. Ours runs nicely at 6,000ppm Salt water salinity is around 35,000ppm so adding SW would soon increase the salinity in the pool.

Some will tell you that too much salt will not harm the chlorinator cell, but I am advised not to do this.

Hence the reason I say in msg 2 that if water runs out and i top up with SW I will remove the chlorinator for the summer, and revert to granular Cl.

Test strips can be used to check salinity, it's very simple.

One advantage with the chlorinator sytem is you only loose the salt if you waste your backwash, I catch mine in a tank and allow to settle, so only dump about 10%, and salt is ver cheap compared to Cl.

If you want to see the system working you are welcome to call round.

Cheers

Brian

Hi Brian 24001,



You really are a "diamond geezer" Thanks for all the info!



Can we use exclusively 100% seawater? The object of the exercise, was the need to preserve fresh water!. The posting from my Maltese friend gave rise to hopes!



I want a clear pool. medically, helpful to asmatics and people who suffer from hayfever.



trouble free, and cheap to maintain.



Where should we go ? and thank you for your highly knowledgeable input.

yes you can use SW, just add the other usual chemicals

Hi Tiggy,



Virgin Converter! I like a man with a sense of humour.



I like fish in the swimming pool! Could we have chips as well



Where is all this fresh water going to come from?



Perhaps if we fill the pool with Efes, we can really enjoy ourselves, when the Government



imposes a ban!.

Pool Doctor,



Is there a sea water option. ie 36000ppm. If so how much?

Hi Wyn & Others,



I posted about seawater pools some time ago as we have long anticipated the fresh water situation we are now experiencing.



We are just about to receive into stock chlorinators purpose built for us for seawater operation. These chlorinators work in the usual way converting salt into chlorine, but unlike normal chlorinators, these will work with salinities of 45,000ppm.



They will work on freshwater pools that have salt added to them to bring the salinity up to 6,000ppm and from that point onwards seawater can be added.



There was extensive posting on this at:

Hi Wyn,



Did you visit the link? All details including costs are mentioned there.



We expect the total conversion cost to be about £1750. The biggest problem will be getting the seawater and transporting it. We need tanker owners who are not scared of carrying seawater.

Sorry Vaughan, I was not specific enough.



My pool is still at the design stage. Hope to build later in the year.



Still considering seawater/freshwater. What would supply only cost be of



the seawater chlorinator?



Thank you,

Supply only of kit would be about £1750 less the £100 installation charge.

Hi Groucho



Depending on the size of your pool it will cost beetween £750-£850 installed and up and running.

Our chlorinators work on salinities from 6000ppm up to 45000ppm and self adjust as the salinity rises.

Standard chlorinators will not work on seawater.

Dear Vaughan,



Your Chlorinators might work with sea water but which pump are you planning to run with sea water may I know.

Vaughan,



Why do the seawater chlorinators cost more than double those that work on milder salinity pools?

Hi Wyn



All people do is speak without knowing nothing about pools. To be abble to run your pool with sea water you will first of all need to change your pump with a Bronze Self Primming pump which is not very cheap in price. Second of all most probably your pool ladders steel specs are AISI 304 which is not suitabble for sea water and will rust in a week and also the same for Nuts and bolts for your lights and main drain.

Hi Wyn,



Your msg 28.



Seawater chlorinators that work on salinities of 6000 up to 45000ppm and adjust automatically across the range are the latest generation in terms of materials and technology. R&D costs also play a part.

Saltwater chlorinators that are restricted to one narrow salinity band have been around since the early seventies. R&D costs have long been recovered.



I hope the above answers your question.



regards



Vaughan
