My current tank is a modest Red Sea Reefer 170. It has been running since October 2016 and supports a varying mix of fish, corals and inverts. It’s as much of a mixed reef as I could achieve on a small scale. The filtration is taken care of by the rock, siporax, skimmer and the harvest of macro algae from a small DIY refugium. I perform water changes every week and use a doser to maintain alkalinity, calcium and other trace element levels. Lighting is provided by a Mitras LX7 LED unit. If I was lucky enough to win a pair of Mitras Slimline units I would use them to start up another small tank with the intention of keeping pipefish.
