Our ground water here is pretty hard. My test kit does not have a hardness tester. Can I just use my fish tank tester? I think it has a hardness tester. Do I have to get a water sample from a certain depth?

Owning the pond is great. Every day when I go out there, even though I am battling cat tails and a troublesome neighbor, my blood pressure drops and everything seems right with the world.
