these are 24 watt over a 12in deep tank. i am thinking of keeping mostly acros but also some different types of montis(digis, caps, superman) birdsnest, hopefully porites and stylopora. basically anything i can get cheap from fellow reefers. but i am still waiting to get stabalized and get rid of my phosphates. my starter sps didnt do well because of that and salinity spikes when i was away.
