Not that I am afraid of SW technology but just never was taught. Have been doing the SW thing for about 6 yrs and was taught the "Old Berlin Method" by a friend of mine. This method is basically lots of rock, a protein skimmer and adequate lighting. Since then I've added an ultra-violet sterilizer, and posphate/nitrate/carbon filter pads but know there is a ton more I need to learn, which is why I am here. Hoping you can all fill me in. Research is all fine and good, but its better to get info from those who know and are using the tech they speak of.
