im really starting to get confused with placing my corals, i have a duncan coral and its open and moving a little but when i first put it in it was filly stretched and exposed and for w.e reason now not the same i have put it in all differant spots and the flow is really the same in most of em i only have one power head in their right now its a 45 gallon tank but i plan on getting another little one to move the water around more but i know the duncan coral doesnt even require that much flow so im kind of confused on what i might be doing wrong here can anyone help? the light fixture is a sola max dual T5 HO
