There are plans for corals, but down the road somewhat. We want to get everything perfectly stable first. Then there's the lighting issue.
Right now we have some CF frankenlighting on there (two random fixtures). We'll probably get MH, although I have been thinking about the LEDs (hmmm... a car or reef lighting...). The lighting will probably mean we have to get a chiller, so it might be a while for the financials.
The next purchase will be an RO unit. The tapwater isn't too bad for FOWLR, but there are phosphates in it.
