How many people use wave makers? And am i right in thinking that they actually help keep the co2 floating around the tank longer. The only reason i ask is that iv just upgraded one of my filters to a aps 1400ef and that just points directly at my fissidens bonsai trees. The other filter points into the flow of that with the co2 on a inline diffuser. My problem is that hardly any flow hits the cuba at the bottom and the more i think its a problem makes me think about getting a wave makers to direct flow to the bottom of the tank. Am i right in thinking its overall flow within the tank and not just the amount thats been pumped through the filter
