I'm looking at the new APEX system controller wifi. Will I ever need to test manually? Nitrates, Ammonia, etc.? I just ordered the DOS system for auto water changes. I'm building a system and buying the equipment over time and will upgrade once I have all the things I need for the larger tank. Currently have a 40 gallon which will become the sump for a 120 gallon tank.
