HELP! Unbalanced Nutrient

[Calcinus]

Hi Brothers,

I need some advice here. I am currently running a 4ft shallow tank and it has been running for 10 months already. My setup runs with a sump that carries protein skimmer, bacteria kings, marine pure blocks, refugium and even a biopellet reactor. However, I am not able to keep my NO3 down. Later I learnt that my redfield ratio is bad because my NO3 is as high as 50 - 60ppm and my PO4 is 0.04 only - high nitrate, low phosphate. May I know how should I restore the balance? otherwise my NO3 will never go down. Thanks alot!

You can start off with 20% water changes first. Carbon dosing isn't going to help much now since the ratio is way off. Dosing de nitrifying bacteria is possible but it will take awhile to see results.  

Also, you can try to run the skimmer slightly wetter. 

 

Hope that helps!!

Your PO4 is ok. As long as it is not zero or above 0.09

You just need to lower your NO3.

Water change has little effect of bringing down NO3 unless we are talking about major water change.

Skimmer is more effective in bringing down your NO3 . So try to run it wet.

You running biopellet reactor . What media you running? 

You have bacteria king and marine pure. Are you dosing bacteria?

I am running NP reducing pellets and I dont dose bacteria. Should I dose?

I read from somewhere that can feed frozen mysis without washing it first to raise PO4?
