0 no3

Hi all :) been wanting to try out this scrubber and have built a DIY system.. but... heres the catch.

I tested and my po4 was pretty on the high side, but my no3 is 0... do u think my scrubber will even work?

Thanks!

Will work fine. Every time to feed, you add both N and P, so eventually they will even out.
