Need flow advice for my 75 gal
I'm having difficulty getting a flow pattern that is satisfactory in my 75 gal. Currently running 2X Rena XP3's. I have tried a few different combinations of intake/outlet positions, but I can't quite find one that is just right. I like a lot of water circulation, but I don't want my plants all blown to one end of the tank.
My last setup had an intake at each end of the tank, and both outlets in the center. This gave good flow (especially since my aquascape is somewhat V shaped with fewer/lower plants in the middle). I did this both with spraybars and with the bare outlet pipes. Problem was that this left the returns sitting "out in the open" and it looked bad.
Right now I'm trying another setup that someone had talked about. Intakes still in each corner. Left side return is a vertical spraybar in the left corner pointed at the front glass. Right side return is vertical spraybar in the right corner pointed along the back of the tank. I was hoping to get somewhat of a circular flow pattern and hide the returns. The hiding worked, but I feel I'm getting a lot less circulation this way.
What else would you suggest. I'm open to any new ideas for my 2 canister setup.
