Have patience?

It's been awhile since my last newbie question. Now it's just a matter of making sure I"m on the right track.

As a refresher -- I have a 20 gallon tank that had been running empty for nearly a year -- no water changes, no live rock, nothing. There HAD been rock and livestock in it previous to that, but they got a bigger tank and simply decided to get rid of this one and gave it to me.

There is a hagen Marine-Glo light in the hood, which I want to replace with a 50/50 Coralife tube so that I can eventually get into corals and such.

I'm still running the Fluval 303, but have added the AquaClear 30 powerhead and have a Koralia powerhead on order, as well as the Nano Rio protein skimmer (which I found out is apparently a piece of poo and craps out quickly, but I'll use it until said day and get a better one later). When the protein skimmer comes in I'll stop running the canister filter.

I now also have about 25 lbs of cured live rock in the tank, as well as 20 lbs of aragonite sand.

I had problems with high nitrite levels until just recently, most of which I attribute to adding the live rock. Everything seems to have finally balanced, and when I brought my water sample in for testing to double check the staff were very pleased (they seem to have gotten to know me very quickly).

So now I have added two snails, two hermit crabs and a conch.

Opinions? How much more of a cleaning crew do I need? Anything I should be doing differently?

Thanks!!!
