I have been trolling these boards for about a month now and thanks to everyones advice I have started and upgrade to a 90 gallon Oceanic Glass mixed reef system. I am upgrading from a 12 gallon aquapod that I have had running for about a year. I am doing a little different setup than the usual tank I am seeing on theis board but I will not be running a sump/fuge system. I am aware of the differences but I believe I can have good success on my choosen route. I will be running a Tunze product called the Combline 500 reefpack. It is three products in one "in tank" setup. It combines the Doc 9005 skimmer (rated up to 135 gallons) an osmolator and a filtration system, all in thank in a compact setup. As far as lighting I plan on running T5/HO's Currnets Nova Extereme 54 watt X 8. I will eventually change out the bulbs but for now I will be running it stock. I am filling the tank with 40lbs of dead porous rock and 30 lbs of live tonga rock. Due to expense I will continue to add LR throughout the cycling phase as I cannot afford to but it all now, eventually getting to 100 lbs. And finally I have choosen to do jsut a 1-1/2" sand bed purley for looks. Because I am not using an fuge I will be using some other products to keep my water quality at it's best. I planned an running multiple (2 or 3) filter media reactors plumbed together and fed with a power head under my cabnet. I plan on using carbon, Purigen, Phosguard. Additionally I was looking into running a De-nitrator again fed by a powerhead which could feed a calcium reactor and then return flow to the tank. I could use one large powerhead plumbed down into my cabinet and then dividing the flow in two directions one to the reactors and the other to the denitrator and calcium reactor. I could put flow control on the lines to control the proper amount of flow to specific units. So at this point most of you are asking why do it this way just use a sump!!!. This seems more expensive. The simple answer is "Piece of mind" I hve 90 gallons of water in my home and I realize that there is a way to prevent overflow or reverse siphoning in the event of power falure, but to have all the water contained and very little plumbing is piece of mind for me.
