Fighting my nitrite stage of my cycle as we speak. I did one 75 pwc tested and it's still high did another 75 pwc an hour later now waiting a hour going to test again and if need be ill do another. My question is how many water changes can I do in one day and my fish not be harmed? There acting fine actually acting happier than when I started. Moving around nicely. Also do I need to wait an hour between tests and refills?
