One time, I tried a filter in my 2.5 gallon tank and continued regular water changes and the ammonia levels shot to high levels! I removed the filter....
He's got a pretty big tank though, I don't think anything would spike super suddenly if he tests the water everyday... And Drax's eye will just get worse in that cold dirty vase... 2.5 gallons are notoriously hard to cycle, anything 3 gallons or less is actually very difficult to maintain. The bigger the tank, the easier to cycle!
