Glad to hear you are fully enjoying the drip system, if anyone needed such a setup its that crazy guy with far too many tanks in his basement. lol, The 500 looks great, that amount of rock looks like nothing in there but im sure it will setup and run good for you fast. I have learned that like freshwater when you take some good old rock plus old water and even substrate and put it all in a new tank it can cycle very fast, my little bio cube seemed like it cycled fully in a week. And building the stand for a very small tank is super easy and sweet. I feel like you, having more mouths to feed is not always a great thing, specially when they it might be something you really do not want or need, especially if they are in a little rough shape. Thanks for the update and the overall info on everything.
