Hey Guys,
Have you used a denitrifying coils with RTCs or any monster fish? Does it work? I came across it on internet. but i would like to get some feed back from you gurus if that is gonna work. I am having a trickle filter and smaller powerhead sponge filter atm. I am thinking now only ammonia > nitrite > nitrate process is working and nitrates are either absobed by plants or removed with water changes. i am thinking, i need to create anaerobic environment to make bacteria break down nitrates. Some guys say that these coils take down the nitrate ppm level by 20ppm or more. Do you have any experience in using these or any helpful comments??
