I do have two pieces of driftwood in there currently. I know the water out here is hard; I don't know if that also means a high kH. I'm just befuddled by the 0-0.25 (apparent) reading on ammonia, that's steady.
Is there another way to test ammonia without risking harm to my tank? I'm just paranoid now, I think, because I'm aware that ammonia alone is bad, but ammonia with high pH is worse.
