Noworries, no worries The manual doesn't read very well. Don't worry about adding more water if you are at 25 - 2600, you actually want to add more salt. (You are at a level that will generate chlorine so add the salt slowly and wait a day or 2 and see what the increase is, the display goes in 100 increments so adding 40 - 60 lbs at a time will give you a better idea of what each bag of salt will do) Please don't forget the cya - I like 30 -40, but there is some debate on this site as to what level is optimal, especially for SWGCs - also Goldline wants you to keep 60 - 80, if you tie the cya to salt at a ratio of 1lb : 100lbs you should fall within my range, but just double it to get to theirs.
