Hi everyone, my first thread so go easy on me! Now to provide a bit of context to the problem, I have a mixed reed and I know everyone says not to chase numbers - which I agree with. But if your tanks a few years old you can easily have PO4 at around 0.40ppm and Nitrates around 40ppm or even higher and everything will be looking great- until you introduce a new coral like some Gonis - which simply wont open under those conditions (new Corals vs exiting ones). Now, I am trying to reduce my Nitrates which are around 32ppm and P04 around 0.13 ppm. I do want to bring my Nitrates back down to around 15-20ppm. The problem is any liquid dosers (for example the NYOS nitrate removal) also actually affect the phosphates. So, if my nitrates go down it will also bring down my phospahtes with them. Can anyone elaborate on the realtionship between these two? i.e. reducing Phospahte -> also reduced Nitrates. reducing NItrates-> reduces phospahates and so on. I dont think i really understand this relationship and I would really like to ! Also, is it actually possible to reduce nitrates without touching phopshates ??
Thanks for your help
