I have been making coil denitrators for the past three years and have finally perfected the best one to keep your nitrates at 0. I still have my very first one I built on my brackish tank. Before I had a denitrator my tank was at 40 ppm nitrates even with water changes every week. They are now at zero and I've saved tons of money on buying salt. If you are interested in purchasing please check out my auctions on ebay: Auction#s 220325300659, 220326104259 and 220326105833 or you could just look up my auctions by doing a search on my ebay user name: gray-havens. The auctions explain coil denitrators pretty in depth, if you have any questions feel free to pm me.
