CO2 @ 120 ppm???
After re-establishing (and deciding to take care of) my tank. I have been taking weekly measurements. Something is wrong. I am dosing Greg's ferts, and pumping CO2 to the point my ph is down to around 6.0. My tap has a kh of 2 and a gh of 1.5, ph around 7.1 or so and a TDS of 45.
After 1 week running, the tank measures TDS of 250, ph 6.0, kh 4, and gh of 6 (nitrates still stubboringly low at less than 5).
A ph of 6.0 and a kh of 4 is supposedly 120 ppm of CO2. Now, I recognize that the chart is not super accurate, but come on, could it really be THAT far off? FWIW - all fish are behaving perfectly normal (other than some clown loaches that seem a bit m ore shy than "usual."
Lastly - It is a brand new TetraTest Laborett test kit..
