Have I cycled?

[VulcanNinja]

Ok, I'm nearing the end of cycling (I think!) and yesterday Nitrite levels were what they've been for a while, about 3.0.

This morning I did a water change and I tested the water about 3 hours later, and found nitrite levels much better. Is that because of the change, or am I almost done with cycling? It was about a 10-15% change. Thanks.

Until that level gets to zero before the water change you are not cycled. TO be cycled you should have zero ammonia and nitrites for a few days in a row while still feeding the ammonia to the tank. So nitrites and ammonia MUST be at zero before it is cycled and safe to add fish. HTH

OK now it's been about 12 hours since the change and Nitrite is 0....I'm crossing my fingers here. It may be over!

I think you're right! It might be over. The nitrites drop rapidly when they finally decide to do so. I'd keep testing for a day or two to make sure the ammo and nitrites stay at zero.

are we talking about your 10 gallon

Yes, my 10 gallon. And some of my brown algae is turning green. Is this good?
