I have had a ten gallon sitting around for a while now. I've decided to try an experimental tank. I'm going to try an all natural filtration nano with just live rock, macro and flow. Maybe one or two small fish and a few snails. My question is I want to fill this thing with marco and have the cost be as low as possible. I was thinking about using a standard shop light with a 6700k bulb like I have over my sump on my 30 breeder. Will that provide enough light for the macro? If not, what is the easiest and least expensive alternative. Thanks!
