I have a 29g biocube. I've attached a pic from the front and left sides before I added anything to the tank. Right now I have my recirc pump return nozzle on the left side of the back wall and a Koralia Hydor Nano on the right side of the back wall. I want to upgrade to something better and more controllable. Both are angled out and forward. Because of my rock work, which is tall, I think an MP-10 would be slamming into the rock no matter where I put it. I was thinking a Gyre on the right side blowing to the left across the top would be good for me. My thoughts are on reliability and function. I know they recently came out with new propellers which are supposed to be much stronger. Does anyone have any experience with the XF130 in a smaller tank similar to mine?
