I used the 7 in 1 test strips and GH, NO2, NO3, CL2, KH and PH are tested. The only one that's close to outside of parameters is the PH at like 7.5. The GH is close to the 0 area as well. We've had the tank for like a month with artificial plants. I believe the tank is cycled not exactly sure. I have done partial water changes to clean up debris.
I did try 4 neon tetras in the tank with this latest betta cuz I saw they were good tank mates for bettas on some online videos. The kids enjoyed them but I'm pretty sure the betta killed them overnight...
