I've purchased a C-vue 40 aquarium and have been collecting parts. My plans aren't crazy as I am a 'low maintenance' sort of person and I want to make it resilient and self sufficient. I've never kept a saltwater tank. My last tank was very successful for 2.5 years before I took it down, and it truly needed almost no maintenance - which I'd like to come as close as I can to that experience. I had a 70 gallon tank with 10 cryptochromis leptsoma cichlids and enough neolamprologus multifacia to have 3 separate breeding groups within the tank. No alge, no water changes, no deaths. It really was a wonderful thing and I miss it a bit. Those little multis can dig like you wouldn't believe. Prior to that I kept a demasoni colony for a few years, but the occasional aggression deaths really turned me off. Fish are friends, y'know? I currently have or have on order the tank, a small skimmer, a heater, and a couple AI prime lights. I have about $550 budget left for non-livestock bits. Things I have interest in are a RO/DI unit, a control system/remote monitoring, a wavemaker style pump, some sort of alge reactor, an auto feeder, and an ATO system. I also need probably $100 worth of rock and sand. Tank will run with a glass top to reduce evaporation. How would you prioritize? I'm not planning to heavily stock the tank - I only really want a shrimp goby + shrimp, flame hawkfish, midas blenny / lawnmower blenny, and one fish that will swim around (flamefish?). 2 maybe 3 coral total (GSP, torch). I could reduce that if it would further the low maintenance goal. Any thoughts appreciated, including calling my plan dumb. I want to have a good course of action from the get-go.
