I've done freshwater for years. Ijust set up a 10 gal nano reef to see if I could do it. Now I'm putting together a 55 gal. I'm trying to make most of the stuff myself. I started making agrocrette rock for my tank. Live rock is just to much. Now I'm trying to put together the lights. There is just so much information out there I need so help. Is the k rating more inportant or the wattage? I can get evrything I need from a local electric supply to put together 4-65wat cf at 6500k and 2-mh at 250 wats for around $250 is this eough? I've also read that you don't need mechical filtration if you put the right thing in your tank is this true. If anyone has anyother info that will be of help feel free to add it to.
