So I just purchased a new hydor koralia evolution 1050. I already have a 750. My tank it a hex front 35 or 36 gallon. My rockscape is in the center of the tank. Ive been reading up on currents and placement and don't know if I have my the best way or not. I tried drawing up a pic with my phone of how I have it now. I tried my best!LOL. The arrows indicate the powerheads, the purple is my rock scape, the black circle is my heater, and the black squares are my Skimmer, fuge, & power filter. (All HOB and in that order from left to right.) Pic is top view illustration. Ant advice very much appreciated!
