I started my 36 bow mixed reef with 15 gallon sump in 2017. I have 2 kessil 360 tuna blues and a current led for fill. I have 4 hydor powerheads with a wavemaker. I have a Rio return pump and a reef octopus skimmer. I use a gravity fed ato with a float valve and use a jebao 4 head doser for my esv doses. I have mixed corals, snails, strawberry conch, melanareus wrasse, and 2 perc clowns which have spawned.
