Diana, that was the best answer I could have possibly imagined. I forgot to mention that I put a piece of driftwood from the well cycled tank in as well.
I'll be picking up a heater tomorrow - and possibly some plants. The lfs doesn't get plants in until Thursday so usually what they have early in the week is pretty limited. Should I start my co2 before I add the plants?
My sponge filter is great with aeration. I had the outflow pointing straight up at first and it shot a water geyser 1.5ft out of the tank.
