Not a new owner but after reading on this site, feel like I am. This is great. I have a couple of questions. First on the BBB method you made this statement...It is also fine to use a salt water chlorine generator (SWG) to add chlorine to the pool instead of using bleach' How do I do this and with what product?? Salt?. I feel like a newbie...my pool guy said I would hardly ever have to check anything...WRONG! It has been 100 plus temps the past 3 weeks and I have black looking stuff in the shallow end. It doesn't seem to puff up like mustard algae...help. I have a vinyl liner pool that is 18x36. Thank you so much.
