I have measured my tank with a Tetra Kh test and get a 4.0. I recently measured with a Lamotte Alkalinity test and it measured a 140ppm which is almost double the tetra test.
I have CO2 injection with a ph controller and have calibrated the ph meter. The ph is about 6.6 which I thought was yielding 30ppm according to the tetra Kh number. The fish are OK which I would believe they would be struggling if the Co2 was actually 60 ppm (if the Lamotte is correct).
My Kh from the faucet is also 4.0. I have3-4" of 100% eco complete as the gravel. I live in the Houston area and the water is fairly hard.
Any idea which test correlates with the ph-KH C02 charts? I saw an old post from George Booth last evening that suggested maybe the tetra test was better. I'm happy with my CO2 system (external reactor) I just want some reassurance as to what the CO2 may be.
I appreciate any feedback.
