i tested the salinty, ph, amonia and everything looks good but I need help with a better test kit cause matching the colors aint that easy and it dont seem precise
I think you need to get some good test kits. The general consensus is Salifert is good. You don't want to do a water change because that will prolong your tank cycling. You need to know by using your test kits if the tank cycled Did you have an ammonia spike? Nitrite?
