So I take care of a neighbors pool that lives out of state. He is here maybe every 6 weeks or so. Well this winter he asked me to cut back to twice a month rather than weekly. Told him ok but at some point would need to go back to weekly. It is time because it is getting hotter and he had green algae in it last week. He still wants me to stick with the twice a month schedule. Not happy about it but it is his pool. Anyone want to chime in with your thoughts or opinions?
