Hey, mouse, I am willing to answer just about every question I can. I can also help you design and build a sump. As far as lighting, I use t5's on my 110gl tank and metal halides on my tanks that are 20-40gl. There are sooooo many factors to consider. I also have some books on reef keeping you can borrow. i think with how much information you are trying to get answered, speaking to someone and research are your best bet. if you want, pm me and we can talk on the phone, and you can even veiw my tanks if you wish.
