Hi mate, thank you for responding so quickly.
At this stage, my plan is to get Aqua One Reef 120 all in one(60cmx45cmx45cm). It has a sump, light, return pump and skimmer. On top of that, I'll get a heater and wavemaker(unsure at this stage which ones). That is pretty much the idea at this stage. So I'll have heating/lighting/filtration/nutrient removal sorted. The only thing left to find out if I need to cool it down or not? and if I do, with what?
As for stock - it will be a reef.
I am planning to get a Starry blenny->2xOcelaris clowns->Wrasse(have a few in my mind, but need to decide which one to get). Also, after the fish will settle I will add a few corals(zoa or two, something for clowns to hug to, and maybe something wavy). Did not think through my corals yet, as it will take months to get to that stage. As for my room temperature - it remains comfortable throughout the year. Sometimes I do turn on AC for an hour or two, but it's like 5-10 days a year when I do it.
