Exactly Papibryn, bad idea draing at this time of year.
Moving on to the contentious part of salt chlorination or direct chlorination.
In France if your pool is used for a gite/hotel etc you cannot use a salt system. The reason is simple and as Papibryn said it won't stop it going green after thunderstorms because they only trickle a tiny bit of chlorine in and it often can't keep up with what is needed to keep the pool sanitised and algae free and it also cannot cope with sudden increases in bather numbers. Use the performance figures quoted by manufacturers as the best and maximum, better to go over size.
With a salt system you are introducing an element of automation that the tablet dissolving doesn't have. Equally if you go for a direct chlorine dosing system it also gets easier.
Cost wise is similar with direct dosing or salt.
Salt chlorinator is moderately expensive to buy circa €800-1200 and uses electricity to run it. The salt cell has a finite life span 5-7 years and cost a fair bit to replace circa €500. Modern units use efficient power supplies but these do not last as long as the older inefficient units. A bag or two of salt at the start of each season €12 per bag
For a similar amount of money you can get a direct dosing unit. the dosing pumps need the feed tubes replacing each season to be safe but certainly every two seasons €8 but you do have to buy your eau de javel so trips to Bricos should be costed in, if you live close this could be less than say the replacement salt cell over 5 years, if you have a long drive then could be more.
Good units have probes for testing the chlorine levels on salt systems and direct dosing systems, these wear out and need replacing every couple of years. NOTE: do not buy cheap probes off Ebay, these last a few months and could cause serious accidents like emptying 15 litres of pH- acid into the pool turning it into swimming in lemon juice, Ouch!
With salt chlorine generators the process causes little bubbles of hydrogen to be given off, these bubbles cause a drift upwards in the pH of the pool so you need a pH dosing unit to bring this back under control. Although a lot of direct dosing units have this pH doser built in direct dosing doesn't suffer from the same pH drift.
Forget about the sales blurb and natural soft water blah blah it's the same chemical soup and the adverts conveniently forget you still have to handle nasty pH- (hydrochloric acid)
Hopefully an overview of both systems, bound to raise more questions and comments, not a problem.
Back to the pool, the pump may not be rated for use in salt pools, some are some are not, due to the corrosive nature of salty water it can cause premature failure if not rated for salt.
Stainless steel ladders can also suffer as can stainless steel screws used on fittings. There are different grades of stainless steel and A2 is most commonly used but a salt pool should really have A4 marine grade.
"No stink of chlorine"
Chlorine doesn't stink, sniff a container of bleach, very little smell just like a well run pool. Chlorine reacts with organics producing as I described previously chloramines (DBP's) these smell as we remember from school swimming trips of the "stink of chlorine" caused by a build up of bad combined chlorine (DBP's) both salt chlorinated and direct dosing pools should not smell, even manually dosed with tablets should not smell, if they do you need to do something about it as the pool is unhealthy.
That's enough from me in one session
