Ok, so I'm ditching the pool store and I'm going to need your help! My pool looks amazing after you all helped me through a nasty algae issue. I had the water tested assuming it would be perfect because it just looks SO pretty! Unfortunately, it isn't and they (of course) suggested that I purchase 4 different products to balance it. I know my first step is to purchase my own tester. Can y'all recommend one that is accurate and decently priced? Ok, for the chemistry...... here are the readings they came up with. I just did a huge dose of chlorine to kill the algae so why am I back down to zero?
