Hi I have a forty gallon breeder that I was thinking about turning into a reef tank. I would be using a marineland penguin 200. For a skimmer I was looking at a reef octopus hob bh100. What size blower would I need? Also, could I do half live sand and half normal aquarium sand to save some money? How many pounds of base rock? How many pounds of live rock? Lastly about how much money would the rock cost me? *edit* sorry wrong category. Thanks in advance
