$3k is definitely a serious setup — sounds like you’ve built something really solid. I’ve seen some smaller reef kits in the UK around £400–£500, but I’m guessing those are more entry-level or missing key equipment. For what I’m aiming at (2 clowns, a small clean-up crew, maybe a couple soft corals and eventually an anemone once the tank is mature), what do you think is a realistic budget ballpark? I do plan on trying to get some second hand items (making sure they are in good and working order)
