I think it is supposed to. I called Brightwell and the owner told me to just switch to CLEAN early. However, I still waited it out.Should the CLEAN help with the nitrite issue? I read your thread and man I hope mine doesn’t take another 30 days! But if it does, it is what it is!
A lot of people believe that nitrite is not harmful to marine life and regardless of the nitrite reading, your tank is essentially cycled after 30-days.
