So I originally had a Maxspect 130 gyre and I loved it, but it had wiring issues and it broke. Since then I was just using my old Koralia 3's and my corals weren't nearly as happy. I eventually bought this IceCap gyre and it was much larger and powerful than the Maxspect. I am having a heck of a time trying to figure out the flow for my 46 gallon tank. I originally had it high up in the tank but it wasn't reaching the bottom underneath so I moved it near just above the middle. I've played around with the power levels a lot and can't find a good medium. It seems like the corals (mostly LPS) extend best when at 10% because it is very little flow, but that is not nearly enough flow to keep algae and detritus from piling up. It seems everything above 20% becomes louder and louder and really blows my corals. Do any of you have this unit and can suggest some settings you use?
