Fishie is in a 5 gallon filtered tank. I didn't cycle it before I put him in, so I've had to do 50%-75% water changes every other day for a couple of weeks.
I test the water every night, and I haven't had to change it since Saturday night! Ammonia and nitrites have been at 0 since then. My test kit didn't come with nitrate testing tho, so I don't know if that's a positive number. :o/
Anyway, does that mean that my tank is cycled? I'll continue to check the params every day, but if ammonia and nitrites remain at 0, how often do I have to change the water and how much?
