oops! Just saw this, sorry about that!
I use my tapwater, which has unique parameters. My TDS is pretty low, for well water, usually around 150. My pH is 7.4ish, but my gh is 6, kh 7 which gives a general hardness of about 115. Their tank temperature is 72, and I do not use substrate. They have stacked driftwood and a lot of anubias and other rhizome type plants. Despite my higher pH, my water is actually considered on the soft side.
No problem. I'll have to check my water and see where I am at compared to yours. I know my pH is around 7.6 and out of the tap my TDS is 100ish. I'll check hardness and see where that's at and go from there. Thanks for the info. I hope I can give these guys a try again without playing mad scientist with water parameters.
