Do plants grow at 0-1 KH?
I checked my water conditions the other day using Red Sea testers and noticed that my KH is at 0-1 (since only one drop of the solution resulted in the "finished" color). pH is about 6.3 and GH is about 6.
Will such a low KH prevent plant growth? I use DIY Co2, but am not sure whether the plants can use it well due to the low KH?
Any knowledge on this? What can I do to safely up KH to about 3 or 4?
