Kh 3 + ph from 7 to 6 = 90co2 wtf??
I have 2 nutrafin plant co2 plant system running in a 41gal tank using the ladders as the diffuser.
Now the thing is my water specs are: ph 7, kh 3. After first co2 system was added = ph 6.7. After 2nd one was added 6.0.
Now the thing is if im right, the co2 chart would be 90ppm of co2 in my tank??? Can this be possible or did i measure wrong?? my fish seem be surviving.
Measured ph using 2 test kits. One gets 6.2(lowest on the chart) and other is 6.0(lowest on the chart)
There is no water movement really, just fluval filter is pushing water stright down.
Firstkit: Using default mixture, bubbles gets smaller to tiny ones
2ndkit: Using default mixture + teaspoon of bakers yeast, bubbles are big and shoots out like 6 in a go then stops for afew secs before going again. Bubbles only decrease say like 30% of their size till they fly of the co2 ladder.
Any one know If this can be?? like its not even pressurised co2 system. Im confused what to think.
