Nice looking tank bro! Is working with the ADA products great or what? I am addicted to that stuff
As for testing I have done a bit on my new set-up as well just to see. Ph & Gh were about where they were in the old set-up (Ph 6.6, Gh 7) & the Kh was 0 (was 5dH). Nitrites were 0 (I used a seasoned filter & a few cups of the old substrate), Nitrates 0.5, phosphates near 0. So it appears that the only factor I can see the AS lowering is the Kh.
