It means you have had the pleasure of using three test kits.:biggrin: Now, you can put the test tube and reagents back in the box and leave them in the cabinet under the tank. The readings you got are acceptable. If you want to know how much CO2 you have in the water, get a drop checker, and set it up. The pH reagent is good for that, and the KH test kit can be used to set up the 4dKH solution in the drop checker.I have just got my Hagen carbonate & general hardness test kit.
What does it all mean.
GH 80mg/L CaCo2
KH 150 mg/L
My PH is 8.2
No, this isn't exactly right. We normally use German degrees of hardness.You have a GH of 8- thats hardness
KH of 15- Your waters ability to buffer the PH- Pretty high
CO2= about 3 ppm if thats what you want to know
