Oops, I meant to tell you....the beneficial bacteria isn't in the water. It's in the filter media/sponges and on the decorations & gravel, etc. So you might want to keep your test kit handy if your filters weren't cycled and you only used pond water. You can't cycle a tank using just water from a cycled tank (or pond), you need the filter material. Maybe you did that, I wasn't sure by your post.perfect_prefect;2134232; said:damn im glad i started it with pre established water. its always nice to have 4-5 thousand gallons of bacteria rich pond water.
