since you are still waiting for the cycle, now would be a good time to look for a bigger tank and transfer all you have into the bigger one. Everyone that I know who has a tank that size really regrets it after a while. there is just not enough room to really get things going and that parameters get a bit touchy with that small a tank. If you can afford it, go bigger now while you are cycling. just put in more water and rock to the new tank and add what you already have. piece of cake now, but a bigger pain later.
