Thanks! I've been reading and will keep investigating. I added dichlor last night but no borax. Today my pH is still 7.6, so I'm thinking I shouldn't add borax unless the pH drops, right? Also, from the simple OT/pH kit (my Taylor kit hasn't arrived yet) it looks like my chlorine is high (though I find this test nearly impossible to read - yellow is yellow to me). Anyway, its a pretty bright yellow - so I'm calling it 3.0+. Is that not safe to swim in? Is there a way to lower it? And should I not add dichlor tonight if the chlorine still looks high this evening?
