Hi Folks - My 90 mixed reef has been up and running for about a year now. I've been trying to adjust (what I think) has been either too much flow---and/or improper placement of power heads. I know that its difficult to move "too much" water for a reef, however, I've noticing some of my SPS le my tank, zenias for example, really look like they are blowing back and forth too hard...I bough a new shroom rock last week and some of the muchrooms have been blowing off. My bubble coral has also been having trouble staying fully inflated, and I read somewhere on the forums that too much flow can/will impact the corals ability to thrive. Anyway--I moved things around this morning and already the bubble seems to be much more filled out. Any thoughts based on past experience would be great!

Let me start by saying your tank looks really nice. I don't think you can circulate too much water but you can certainly have too high a velocity of that water. As far as adjustment of flow goes I feel it's what one would consider fine tuning their tank. Not only different species but individuals within that species are going to like different flow rates. You can get a general idea of the flow rates that a species requires from various books and/or charts. But again I think it's fine tuning and you need to observe, over time, what works best for your individual specimens. I am constantly changing the velocity and direction of water flow in my tanks as I add individuals or move them around. I know this dosen't answer your original question but sometimes there is not a exact and difinitive answer.
TomIt,s the very things we think we know that prevent us from learning the things we should know.
