Okay, I now know Aqua Soil is messing around with my PH so my drop checker is sort of cheating on me at the moment

and a test using KH and PH won't really be accurate.

But, as I did a CO2 test a few hours ago after 18 hours of zero CO2 injection and 3 hours of surface agitation, at least I have something of a benchmark.

This was the earlier test,
pH 6.8
KH 2°/35.71 ppm
CO2 level 9.51 ppm approximately

5 hours later at the end of my photoperiod and a bubble rate of 1 per second, this is the results.
pH 6.2
KH 2°/35.71 ppm
CO2 level 37.86 ppm approximately

PH fell by 0.6 due to the CO2 so at least I can see a rise in the CO2 level. I dun know how accurate is the 37.86 ppm but at least there has been an increase and an average gauge of my CO2 levels.

Here are my other test results for Day 4.

PH – 6.2
GH - Did not test.
KH – 2
NO2 – 0.8
NH3/NH4 – 6

What is very interesting and significant is that NH3/NH4 is going down and at the very same time, NO2 is going up. That can only mean one thing, Nitrosomonas bacteria has come alive and the nitrogen cycle has started!!!

All thanks to the heavy dosing of Seachem Stability in the last 4 days and my wonderful Bio Rio.
