Bax - Thanks for your input. I checked out the Digital Aquatics Reef Keeper you mentioned.

Wow, this thing looks awesome! I compared it to the Medusa temperature controller and the AquaController Jr. For the price and functionality, it looks hard to beat. Love the feed mode. It also looks quite simple to use, is this the case for you? Thanks so much for the suggestion, I think I can see this device in my cabinet. I wonder if I could use this with the IceCap fan mentioned above? Anyone else out there have experience with it? I'd still like to monitor my pH on a continual basis, maybe I'll get a Pinpoint pH probe as well.
I'm not permanently discouraged by the goby/shrimp pair, as you will soon see

bcoons - Glad you've had success with the relatively "early" additions to your tank. I was, in my opinion, quite cautious since I was not interested in killing a lot of fish, but look where that got me

I guess it just goes to show you that this is as much art as it is science, and we sometimes have to make decisions based on best guesses, supported by the data that's available. Even though I thought I was being conservative by waiting 2 months before adding a fish, others would say that this was too early. Here's what Eric Borneman said in this thread

You could add fish shortly after the cycle is over. If I were you, though, I'd wait 8 months or a year.
Regarding your questions:
1. John (thedude15810) doesn't use a QT either, and he's had great success with his fish. I didn't get one until after my next loss, which I'll explain in a subsequent post. I think the number of benefits of having a QT markedly outweigh the risk of putting a sick fish into my display tank. On a very basic level, I also enjoy having 2 tanks to fiddle around with.
It sounds like you have all of the necessary ingredients to get a QT up and running. As far as the question you asked regarding the biological filtration (bacteria), the answer is not with LR or sand (although there are several folks here on RC that DO use LR in their QTs - check out this thread
http://www.reefcentral.com/forums/showthread.php?s=&threadid=699502&perpage=25&pagenumber=1). Simply place the filter sponge from your HOB filter into your current tank's sump and let it sit in there for a week or so. The sponge will become colonized with all of the healthy bacteria your QT will need, so you'll want to transfer this sponge into your filter while running your QT. This doesn't mean you don't have to do water changes in your QT, but at least your tank will be able to handle the wastes from your fish and uneaten foods. I have extra sponges and always keep one in my sump. That way, if you have to medicate your QT and the sponge becomes "contaminated," simply throw that one away and use the new one from your sump. They're quite cheap. This also ensures that you have a sponge populated with bacteria in a pinch for that impulse buy from the LFS. I think that most people recommend you tear down your QT between uses. This ensures that it's cleaned between acquisitions, and it should be quick and easy to setup for new fish, assuming that there's a filter sponge in your sump

Here's another good QT thread, for those interested.

Here's something I was wondering ... what if a fish is in quarantine for 4-6 weeks, then is added to the display without ever needing medications. Is it OK to immediately add a new fish to the QT without breaking it down? I would think it would be OK as long as the filter sponge and carbon were discarded and replaced (?).
2. I'm no moonlight authority (I'm no authority, period!), and I don't know the specific watts/gallon that are recommended. I know that the ads for moonlights recommend running them the entire night for improved coral growth and stimulation of spawning, but of course they're trying to sell a product. Melev sited some data implicating moonlights and coral bleaching, so I guess this deserves some further research. I like his idea of turning them on/off as needed.
I hope you will investigate the automated controllers, you know, being an EE and all, and post your recommendations here! I didn't think I'd ever need or want one for my little 30 gal tank either, and 3 months later look where I am

Now is anyone going to tell me how to post a
