Hi everyone, I used to be active here, over a decade ago, when I kept a huge reef tank. I have not had a tank since then and now want to get back into it again, but I want to go small. I would love to get a ready made complete system, if there is such a thing that actually works. I don't want to kill fish and coral. Looking to create a nano with a few corals, invertebrates and small fish like gobies. Is this possible with todays technology?
