Hello, I'm a new pool owner so I'm still learning the chemistry involved in maintaining a pool. Since I didn't trust myself yet we hired a service to maintain the pool. Just out of curiosity and for my own learning I bought some test strips and I'm concerned about the chlorine levels. Here are some details about the pool:
Hayward pump and DE filter
I used two test strips, one by HTH and the other aquacheck 7.
On the HTH stick:
Free chlorine maxed out 10+ppm
On the aquacheck :
Free Chlorine 20
Total chlorine 5
Do these numbers look OK? The pool is clear but I'm worried about too high chlorine. I apologize if I left out any information.
