lowering pH
I have a 30 gallon tank with several mostly tropical fish in it, and I think the pH is a little high. The water is definitely hard too. I'm wondering what I can do to lower the pH and / or make the water less hard? I don't really want to buy any new devices, but what can I put in the tank or filter? Would putting wood in the tank make it less hard and more acidic?
