    Default Flow on a 70G Cube

    I have a 70G cube that I was using a MJ1200 mod. It had a pretty strong directional flow that was too harsh on my corals. I have softies, leathers and LPS. Recently, I purchased a Koralia Evolution 1050 and love the dispersed flow. My question is: Where is the best location to put it? On the side pane or the back? I have it on the back corner right now. I have 1 directed flow returns in each corner. I want to be sure and have enough surface agitation so i pointed it up. The frogspawn is very gently moving, not much at all. The blastos are fully distended and open. The yellow polyps are fully extended but not swaying. These are in the middle portion of the tank. The Duncans are at the bottom of the tank and they have a pretty good movement to them. Do you think I need another powerhead to point downward towards the middle of the tank or should I move it to the side?

    Cubes are a bit different. I had a 90 long before and had them on each end of the tank. Just trying to figure this out. Wondered if anyone else has a cube with Koralias?

    The picture I am including is when I had the powerhead pointed down but there was not surface agitation so I was concerned about not enough oxygen. The yellow polyps you can see are blown pretty much to the side.
    Thanks in advance.

    Personally I'd put it on the side pointing up. The flow will then hit the opposite wall and come back around. Just my .02

    i have a 30 gal cube. my tank is set up for some difficult to keep fish that are not appropriate for reef tanks, but i do have 2 korailias (420 and a 240) in there. i keep them both on the back part of the glass, at the top, pointed slightly down creating great laminar flow. this keep food suspended for quite some time and makes the most out of my feedings.

    I am thinking of adding a 750 and putting both on the back. Then they will be hidden on the black wall. Here is video link to see the movement now with it on the side. I am just not sure there is enough flow. I know there is too much on the Duncans. I will have to move them

    I was wanting to put them both on a wavemaker timer and see if it will make pulsing wave motion. Anyone tried this in a cube of this size before?

    Thanks to Chris, i got another Koralia Evolution 750. I was able to mount both on the back wall halfway down the tank and point up towards the surface. Good agitation on the surface now and the flow is dispersed nicely. At first I had them pointing toward each other. I used a baster and cleaned off all the rock. Man! Those things kept all that matter suspended forever! I was afraid I really messed up.
    I moved them so that they weren't pointing at each other and walla! Finally, the particles were able to move to the sump and go through the skimmer. Tank is perfectly clear now.
    I had too much flow at the bottom of the tank on my Duncans. I tried to move it over where there wasn't so much flow. That silly thing just would NOT stay in place. I tried 2 whole tubes of gel glue. Finally I got it in place. I really need to buy some epoxy but I don't want to make it permanent until I am sure it is where I want it. Those Duncans have slimed me, shrivelled up and are extremely unhappy at the moment. Hope they perk up soon.

    It was really nice meeting you Chris and thanks for tips on my ATO.

    Well that video didn't work.
    I also have a picture of the clear mesh screen I installed that Bay City Reefer made for me and the look without the canopy.

    Got my wavemaker in today. The corals seem happier. The Duncans are fully open and you can see the green and their mouths now. The Frogspawn is gently waving and the polyps are are standing straight up.

    I'm not sure how to load this video but will try. Hope it works.
