Kat, everyone is trying their best to help by sorting out the info you're giving.
The fact still remains that you need to get your own (quality) water parameter test kit, not test strips, not the LFS.
You still haven't stated what water dechlorinator (if any) you're using, what type of filtration you run, what type of bio media it may have and how you maintain it. These are all crucial things to maintaining proper water params.
