OK--so my 20g tank has been up&running

[Good Crab]

for a month now with live rock. When can I start to add some coral? I have nothing in the tank except hermit crabs, a peppermint and some snails.

For some reason Nitrite is still .25 but are not affecting the animals. Should I wait until that goes to zero? All other water parameters are good. And I have lots of water moverment.

Coral should not be added for several months. Something is rotting and causing the NO3 reading. You need to get that to zero and start with a small fish before even considering corals.

Thanks for the reply, Brenden. Can't imagine what is rotting. So I should wait a few months? I only want one [1] fish. (Clown)

Double check your nitrite reading, but yes, nitrite should be 0 before you add either fish or corals.

As reefrunner said retest. If it is still .25 I would think it should zero out in more like a week or so, not months.

Jsut do a few big water changes then give it a week and do anotehr reading.
