I think i am having the same issue as this guy, with the plants... I have a 3 gallon eclipse that I started just about a month ago with a zebra danio, some java moss, and some java fern. went on vacation for the first 2 weeks that i set up the tank :thud: and came back and have recently been testing the water and im getting 0.6 ammonia and no nitrite at all. Perhaps the thing cycled already while i was away? But then what accounts for the ammonia reading.. ive been changing the water every few days.
