Update, the skin is actually healing over the burns on his head. I still catch him watching TV often and he stares at the cat like he wants to kill it. Cat could care less.
It's only about an inch in each tank. I prefer bare bottom but my wife like the look of sand more. I have a lot of flow in all my tanks and it's set up so very little collects in any one spot.
I've been reefing for a little over 2 years.
I spend maybe 15 min a day working with my tank. Water changes take 30 mins. I have a 120g tank, 29g tank (both Reef tanks have softies, lps, sps and anemones) and QT tank. I spend 5 mins checking on my chameleons every day.
