Thanks @
leodb89. Nice to get feedback like that on occasion, especially when some days I look at my tank and think I'm screwing it up. Funny how you say that about my tank though and I spend my time thinking exactly the same about yours :)
It is a Reef Octopus 500 and I'm pretty happy with it. Not sure about the Deltec in comparison but I know the Reef Octopus comes in at nearly half the price. Being a small cabinet and an even smaller sump, I was pretty limited with my choices. Value for money vs meeting criteria it came up trumps.
Maintenance routine I think would be stock standard. At least 10-20% WC per week, daily alk dosing, and daily feeding with either frozen or nls for the fish, and mysis for the corals once or twice a week. Just bought some reef roids to have a go at so I'll post results in due course.
