I'm in the same situation, with parameters similar to what speakerguy posted.

I have not yet calibrated my test kits to know if they are accurate or not. My PO4 says 2.0 from tap and PH is 8.0-8.2 after aerating(7.4 straight from tap)

So far I have plants growing in my lower lighting non co2 tank
