Lets get into this, I started my tank in January of this year with a DIY CO2 system, I've actaully kept track of my CO2 readings from then,
My PH was always between 7.0 & 7.4
KH between 6 & 8
This put my CO2 into an understandable position
I must note that I wasn't dosing ferts using the EI method
I would usually dose Flourish and Nitrates 3 times a week.
I then went pressurized and started the EI Method
now I can't get a CO2 reading that makes sense.
I've tested PH with both Redsea and Wardley, test results are both the same
Tested KH with Redsea, always 10
Tested CO2 for the heck of it with Redsea stopped after adding almost 20 drops into the test tube because I knew that it was putting me at an insane CO2 amount again, and now from reading the link Shalu posted, I see CO2 tests are far from foolproof.
I just find this really interesting, Whats causing this?
I don't want to get to crazy with this topic, I know that many people have pressurized CO2 and dose ferts using the EI method,
My chemistry for whatever reason has changed from this, and like I said, my tank is healthy, just wanted a CO2 reading to try and stop BBA, so when I thought about increasing CO2 wanted to test to see were I was.
