    In my 55 gallon reef tank, i have lots of flow; a Koralia 1, 3 and 4 along with a return pump at 250 gallons/hour. I total about 2700gph and there is lots of heavy flow; but the thing is i cant find anywhere to put my frogspawn, hammer and another softy. They just will not come out very much. Parameters are in check, GSP, zoos and everything else comes out. Should i rearrange the koralias to try and create a zone of lower flow for them?
    What shall i do

    IMO those softies should be coming out. Maybe try them by the Koralia 1 first. I have 2 Koralia 2's but I have dual returns with split hoses on my 120g. I try not to give them direct flow. They move enough on their own. My frogspawn will come out in any current, I'm somewhat puzzled?:-/ Good luck.

    Yea i think Im going to have to do some rearranging, I have three corals (hammer, frogspawn, and alveopora) which all prefere low current and I have lots of flow in my tank. I think im going to have to creat an area of low flow for these guys. Im try to accomplish this in a bit.

    Well, your flow numbers are pretty much by the book. And your choice of powerheads is fantastic. K+. It gives you the ability to really change the flow in your tank and fine tune. So, yeah, rearrange and go with it......

    I have mine below the power heads, that way they get a good flow (from suction) but not a direct flow.

    So i turn all my flow off except the return pump and guess what happens, all my softies start coming out. Hmph, I have to create a low flow zone

    Point the PHs originating in the corners of the tank and try placing the corals that don't like flow directly under the PH, as that will have the lowest flow area for them. Leave the PH high enough so they won't get sucked up into the impellers though.

    Well this is what i did and it has worked. YAY go me. I put the Koralia 4 3/4 the way up on the back left pointing upwards and the other two koralia's on the right side, the small one point to the front and the larger one to the back. I have 90lbs of rock anyways and the flow is broken up and very little underneath the left side. All my softies are there and they have begun to come back out again. Yippee

    thanks everyone

    Only one thing. I've heard by another reefer and I don't know for sure the accuracy of his statement and if anyone can supply validity either way this is what I heard. I was told to not aim the pumps into the rocks because that is an area the fish view as their asylum from the waves. A place to rest and sleep. Does this make sense err.. yes. If I was a fish I might view it that way.
    IMO flow is subject to debate so I just try to think the way I think a fish thinks. You've got returns pumping out flow for the corals on top. The Koralia's pump flow to the corals on the sides and they all carry somewhat to the front where you put the corals that don't call for much flow. Like you said when you turned off the Koralia's your corals came out. Listen to your corals but the flow is good also for filtration. Once a month or so I'll hand aim a Koralia into the rocks for a short time to loosen dirt and old food and wait a half hour and change my floss. This my friend is what this hobby is all about. Planning is the trick. Just one man's opinion that's all.;)

    To add to this topic, I have a little over 2,000 GPH in my 18 gallon(which i'm pretty sure if i did my math right is really 20 gallons), doing the math I should have a bit over 100 gph overturn rate. I rescued an elegance coral which by all means does not like ANY type of hard flow, but he has been doing quite well and has been open consistently every day. Not that this can really help you at all, but just try rearranging them and see what can/won't work.
