I'm a total newbie to this site and to my new gunnite pool that has a new salt generator system.
The builders, who have also provided basic service up to this point, have told me to just add muriatic acid daily ( 1/3 of a jug) and no shock now that the salt generator is up and running. Actually it's been running for a couple of weeks. Soon after the SWG was installed I started to notice some algae on the pool walls and especially the walls in the spa part ( both are white plaster). The tech came by and added about a half a bottle of algacide and things were good for a coupla weeks. I brush the pool faithfully but after the last heavy rain the algae is coming back. The water is crystal clear but I'm paranoid about damaging the pool so the only thing I've done is tonite I put in a pound of powdered/granulated(?) shock. I was shutting off the filter for about 6-8 hrs nightly after midnite about the time the algae started appearing.
I welcome any and all suggestions. Thanks
