How long did your cell last?

Chlorine is a strong oxidizer and if not buffered by CYA it can cause issues. Chem Geek had posted about this on several occasions. A quick search revealed this:

It is well known that high chlorine levels (especially in indoor pools without CYA) are corrosive to metals and that high chloride levels accelerate stainless steel corrosion (see this post).
Those are known mechanisms with the only issue being the rate of such corrosion in 3000 ppm salt pools. It has been proposed that stray currents may also be to blame, but no clear mechanism for that has yet been found and that would not explain corrosion of the metal parts in a pool cleaner, for example, since there is no current flow from the electrolysis in the salt cell possible in that case -- the metal is just exposed to salty, chlorinated water and is not electrically connected (and such corrosion in non-SWG pools is still in salty, chlorinated water, but with lower levels of salt). If the bonding wire and all metal components were to have a positive voltage applied to them, then there is no question that metal corrosion would be greatly accelerated.

As for your decreasing salt level, it is either a leak or splash out. You have to be losing water (other than evaporation) for the salt level to decrease.


If your readings are changing a lot or the cell sometimes works or sometimes doesn't, it could be the solder joint issue:

Sorry I haven't come back sooner, just found this going through my old emails. I found out after my last post that the lost of salt was happening because of a leak in the main drain . So I shut that side of the return lines and I'm just using the skimmers. Thanks Mark for the links I'll try to read them all when I have time.
