Okay I just tested my cichlid tanks level they are gh 180, kh 180, ph 7.5, no2 1, and no3 40, do I need to do any thing to change levels?
Water changes, nitrate should not be above 20ppm, even before a water change.
Test your tap water's nitrate.
No it isn't, it is only worth throwing out. You can guess more accurately than strips will tell you.
