This question probably got asked a lot. But my tank is 4 months old. Lps dominant tank. Everything doing great. But nitrate keep going down. Im sitting at 8.6. From 9.6. I dose all for reef everyday 20ml half the recommended dose for my tank. I read that all for reef act like carbon dosing, and take nitrate down a little? Not sure. Its a 150G. Total water volume 200G tank. I have couple of fish. Any recommendations?

lots of options -

  • feed more
  • reduce photoperiod for refugium or algae scrubber, if you have one
  • more fish
  • nitrate dosing (I'm not familiar with this, I'll leave commentary to the experts)

I use this. Sorry I don't remember the ratio to RODI and am not home. Nice thing about raising nitrates is that you can do it quickly. I've raised as much 5ppm at one time.

EDIT : personally I don't see a problem with yours. Your tank is young and hasn't really stabilized yet. Many tanks will eventually settle in at certain level and stay there. I have one that runs 15-20 another 5ish ppm and another that's barely detectable but I do a form of carbon dosing on that one and am keeping N and P low intentionally.

8.6 ppm nitrate is more than enough. But if it continues down, feeding more or dosing a source of N (food grade sodium or calcium nitrate, ammonia, or amino acids) will all halt the slide.

There’s no need or benefit from a commercial product such as expensive. Neonitrate that lacks any purity or composition guarantee.
