Aquarium Advice Addict
I've been doing research on keeping discus and come to understand that they don't handle high levels of nitrates. My tap water at times will come out with 10 ppm nitrates. From what i have read, that's too high for discus. As a result I've been looking into a denitrator. Most of the info I've found relates to saltwater tanks. I have found this site for a commercially made denitrator: Aquarium DeNitrator, Denitrators, Poseidon X1, X2, X3 Denitrator systems ; Nitrate Removal Filter . Does anyone have any experience using a denitrator in a freshwater tank? If I understand what they do, does that mean that I won't need to do water changes in an established tank? What are the risks/drawbacks associated with using a denitrator? I also found this site about making your own denitrator: DIY Coil Denitrator Plans - DIY Coil Denitrator Plans . Again, this info seems to be directed at saltwater enthusiasts. Really would love to here from someone that has had actual experience with using some version of a denitrator in a freshwater tank. Right now I'm thinking of adding one to my 60 gallon community tank as a test prior to jumping into keeping discus.
