eugenet, no need to apologize at all, I just want to make sure you are getting balanced info and understand that in this hobby one size truly does not fit all. *cough* ferts *cough*...
I am doing hight lights and injecting fermented CO2, but I also have a full cover of duckweed that filters some of those watts.
I love my aquaclear filters, but if you don't like surface agitation, they can be your mortal enemy, especially as the water level drops a bit. I found that the cheapo whisper 10 that I have in the tank I posted has a near perfect water return that seems to push the water flow along the surface horizontally as opposed to cascading it down vertically or at a sharp angle (even when the water level drops a bit). Probly cause it has a nice lip on it. I'm not as big a fan of the filter media in the whisper, but it's a trade-off.
One little tip I can give you that might be unorthodox, but hey, I seem to be a rebel around here anyway. When my wife was griping about how my aquaclear would annoy her at night since the water return was loud, I would prop a fish net under the flow and it would make it perfectly silent, as well as virtually kill the agitation. Ideally one could use that technique during the day when you don't want agitation, but at night remove it to release some of the CO2 that the plants are now releasing. In a perfect world I would patent such a device and sell it to HOB naysayers, but I'm too busy chatting on forums these days to do anything productive.
