My filter came with two different set ups for the out put of the water. A trickle bar with holes in it and a jet nozzel. Ive got the Jet nozzel right now pointed towards my single 200W heater so it will spread the heat evenly. The nozzel is submerged about 5 inchs under the surface of the water and I can see the water ripple on the surface of the water but not very strong... My question is should I have the nozzel closer to the surface to make more of a wake?
