I am always interested to learn what non traditional or even downright heretical reefkeeping practices folks pursue. As many here already know, I am often trying to determine the minimum of equipment that may be required to maintain an awesome reef. In speaking with Jackson (Jacksonpt) yesterday, I came to learn that he keeps his beautiful 30 gallon mixed reef with no skimmer (albeit withj a small bioload). I myself maintain a 30 gallon reef at my work office with only a small hob skimmer and a hob mechanical filter. It has less nuisance algae than my 125 gallon display with a sump and G-3 skimmer. I also maintain a very packed 75 gallon mixed reef with no sump, a hob skimmer and a Fluval canister filter. I use no calcium reactors and all top offs are manual. I get crazy growth on all systems. This does not mean that I recommend these practices for others but they have worked beautifully for me for the last 5 years. I am curious to see what other "violations of reefkeeping law" folks havew been pursuing.
