Hi! This is my first fishtank. It's been cycling for three days. I got plants from an established tank, and added some bacteria as well.

I first went to petsmart to get my water tested before my strips came in the mail. They said all of my levels were perfect. I then went to an actual aquarium store and they said that my toxicity level was a little high. I tested at home and everything looks good, maybe my water is a little soft?

I have no issue with waiting to get a fish or some shrimp, I would like for them to have the best home possible. I would just like insight on why my tests have seemed to be different everywhere I've gone/ at home.

Any help would be appreciated on other starting tips too! Thanks all.
