I recently bought a house that has an inground pool... It's 20'x40' with an 8' deep end and like 3' shallow end... It holds about 30,000 gallons. It has a chlorinator that I keep full and have turned on to 4. It goes up to 8 but I don't know what I'm doing so I just set it at 4...

Anyway I bought one of these hth 6-way test kits and it looks like my chlorine is high but my ph is low... I'm trying to figure out what I need to do from here.... The water in the pool is clear.

If I can figure out how to post a picture on here I'll post a picture of the test kit and my sample with the OTO and phenol red.

Thanks for any and all help
