I'm running my tank without a skimmer. I do 7% water changes weekly, and drop a bag of carbon in the tank for a week or so out of the month. My nitrates right now are at 0, but the tank hasn't been running all that long. I'm interested in getting something that'll do OK with slightly high nitrates.\r\n\r\nMy tank is a 47g tall, tank depth is 33". I have a 150w MH for lighting.\r\n\r\nIf anyone wants to toss out a list or so, so that I have something to plan off of that'd be great!\r\nCurrently:\r\nFrogspawn, zoas, button polyps, xenia, and some kind of clove looking coral that forms hard tubes..got it from my dad when he took his tank down so I don't really know much about it.\r\n\r\nHere's a pick of the tank before I had the MH on it.\r\n[IMG]http://i689.photobucket.com/albums/vv253/Gdbyrd/IMG_1004.jpg[/IMG]\r\n\r\nThank you!
