CO2/PH/KH Relationship
"Frank Mamone" wrote in message .. . 1) Will filtering with peat help the plants? 2) Will the peat affect Co2 calculations using the PH/KH? I know phosphates will. Depends what you mean by peat filtering. I prepare the water for my tanks through a peat filtering rig I built - makes me about 50USG at a time - I use ordinary garden peat. What I found wast that after the initial filtering there was massive (100-120ppm) amounts of CO2 in the water which then disperses over time as you'd expect. Therefore what I do is measure the KH as its working and when that comes down to where I want it (about 5 DKh) then I stop the thing and then just circulate the water till the initial blast of CO2 has worn off.. WHat I then find is that the relationship between KH/PH & CO2 levels seems to work perfectly well. i.e. the Ph has beeen reduced along side the Kh by a predictable amount. When the water is in my tank the PH is then reduced further via CO2 injection - the KH is stable. If you were referring to using Aquarium peat in your filter then I have never used it so can't help - although I would think the effects would be similar though maybe less dramatic. rgds I. |
