yep do a change whenever you see ammonia or nitrite in the tank; its just the tail end of the cycle...very soon you should be stable.
sorry for asking if you have answered this already but have you checked your tap readings for ammonia, nitrite and nitrate ?
Yeah I checked the Tap a few days ago
I had 0 amonia 0 nitrite and 10 nitrate
Did another water change last night
Tested again just now and still have between 0 and .25 amonia
0 nitrite and 10 nitrate.
Gonna do another WC again when I get home from work.
