I searched before posting but the results weren't very useful - the search routine only searched for the keyword 'salt' in my seach request of 'salt without SWG' and similar variations. 'without' and 'SWG' were deemed too common to be included by the search routine. Of course every thread in this branch of the forum and then some were returned. I then browsed manually through all 10 pages of this branch of the forum and only came up with this thread: http://www.poolforum.com/pf2/showthread.php?t=2740 which obviously is not the one you're refering to.

If you could direct me to the long one that discusses the issues I'd be much obliged.

Thanks for this great resource. I've been pool store free for a year and a half now and my pool has never been better!
