If you have a sump then its simple a coil denitrater will fix the problem I have never had an issue with NO3 in all the yrs I have used these .. If you do not have a sump then you have to force feed the water through the coil with a pump rather then siphon and they work 100% .. Thats the short and long of it. Now it can be made complicated to rid the tank of NO3's and many do.. (: If you need one ?
