mayenne53 Posted April 2, 2007 Share Posted April 2, 2007 I dont mind saying it is Waterair - not some small company by any means, and I WOUNDN'T recommend them. So, chlorine and liners....the risks?? Link to comment Share on other sites More sharing options...
Poolguy Posted April 2, 2007 Author Share Posted April 2, 2007 Well I can tell you this....There are a number of Companies who are pushing this line that you must usetheir chemicals - which in Europe I believe is illegal as it is untrue. I defyWaterair, Desjoyeaux or any other similar Company (engaging in these practices)to prove that using the correct balance of other brands of chemicals hasdamaged a PVC Liner. I know I am on safe ground because it is IMPOSSIBLE toprove (evidence- testimony from liner manufacturers - Ankorplan 2000) I wouldventure that if some person were to challenge their claim in court then theCompanies which use this claim would get a right slapping. The charge against them would be restrictivetrade practices and its looked on with some distain by the judiciaryDamage to the liner (apart from the usual abuse) can be caused by: pH being out of balance for a considerable period of time (years). The liner and all other gaskets and so forth will grow and therefore create wrinkles and creases which will eventually leak.Chlor gallets/pastilles being thrown into the pool and resting on the liner instead of being put into the skimmer box to dissolve. Resting on the liner they will create white 'burn' marks where the liner is bleached. Apart from being unsightly these will become a weak spot and possibly the site of a leak.Excessive calcium build-up will make the liner stiff and occasionally brittle, but it takes years and it could be just as easily be caused by UV.Other than that, using any brand of chlorine and pHbalance (+ or -) will do no harm to a PVC liner whatsoever.What you definitely must do is to keep the water balance correct and the chlorconcentration correct. Whether you use their chemicals, or gallets from thesupermarket or Javel (sodium hypochloride) and acid (sulphuric) is of noconsequence to the liner what so ever as it is the same (almost). That is notto say that all products are equal as they are not.Most of the Chlor chemicals available in the shops are a mixture of Sodiumhypochloride and Cyanuric acid viz; Acide Trichlorocynurate, (chlor choc) orAcid Dichlorocynurate (chlor lent). this is not a problem if you are checking semiregularly for Cyanuric acid levels (they must not pass 50ppm) but if you arenot then it can be catastrophic for the water quality.I prefer (as you all know) to use the purer Javel (sodium hypochloride) and addcyanuric only when the levels drop do to rainfall or dilution of some other form.This allows for more control and therefore better water quality and lessmaintenance.Andrew Link to comment Share on other sites More sharing options...
mayenne53 Posted April 2, 2007 Share Posted April 2, 2007 Hello AndrewWell that is very interesting and good news, as their Chemicals are very expensive. And, the funny thing is, even though they state that no Chlorine products can be used, the 'blocks' they provide for the skimmers smell like a Chlorine tablet! When you say Javel, is that like the ordinary Supermarket Javel (bleach) or a stronger concentrate - I seem to remember that the store ones are around 2-3% sodium hypochlorite.I do check and maintain my PH +/- regularly. Where do you normally obtain the Acide Trichlorocynurate from?thanks for your advice so far..Jamie Link to comment Share on other sites More sharing options...
Poolguy Posted April 2, 2007 Author Share Posted April 2, 2007 Yes it is uncanny the seeming contradictions in the propositions of some pool Companies in France.If you tell me where in France you are by PM then I can guide you to shop for the good products.The Javel I use is 9.6% active for domestic and 12.9% active for commercial (public)Its available from Brico's generally.I'm happy to have been of help.Andrew Link to comment Share on other sites More sharing options...
