First timer over here. Need help
okay so I bought the house last year. pool was ready and great. super easy to maintain basically just added some bromine tablets, the odd shock and vacuum periodically. closed October and opened 4 days ago. (I paid someone to close it, same person as old owners..)(I opened myself)
ive added more chlorine then I though you would ever need (6 of those jugs) , brushed twice a day and backwashed sand filter every 20 hours as its needed based on my understanding of the pressure hitting 14 psi higher the normal (14 increases to 25-30)
I feel like I’ve made no progress.
I got water tested at local store they said just keep brushing don’t bother adding anything new right now.
please help or tell me if I’m on the right track.
