Hi yes sorry forgot to mention water flow
yes most set ups have loads of turn over,using pumps to simply recirculate the water. As for the anemone i would wait on that one as they are quite demanding and need perfect water,so i would look to have a FOWL set up = F = fish, O = only W =with, L = living rock. so that means the 'rock' filters your tank,you just need a filter for removing solids and phosphates. A phosphate remover is just like carbon. Solid removing filter is simply some sponge or equivalent.
