Question 1 of 3
 
What should the ammonia, nitrite and nitrate levels be on a cycled tank?

Did you see this article about cycling your tank. Lots of good info: http://www.tropicalfishkeeping.com/f...-cycle-213418/

Ammonia:0
Nitrite:0
Nitrate: 40 maximum (less than 20 is generally considered healthy for the fish)

Nitrate levels are totally debatable. I know mine are at least "40". I put it in quotes because the nitrate test is the least accurate of the three.

0,0,0 with occasional bumps up of nitrate.

Of course that assumes plants are thriving.

Assumes there are plants at all.

thanks guys, I was worried as nitrate had dropped to 0, nitrite and ammonia just above 0, but that will be solved with water change tomorrow.

Yes I have plants there going well.

sounds good.

sometimes after nitrates (finally) drop to 0, you get cyano bacteria blooms. If that happens just kill the lights and stop adding food untill it dies off. Then resume with 1/2 lighting and feeding and adjust so the plants thrive but the cyano stays away.
