ran a water test and noticed my ph was a little low - 7.4ish, maybe a little higher. I had heard about using baking soda, but wanted some advice before I ran out and put anything in my tank. I know I can get all sorts of "ph correct" buffers through an LFS or online. however I'm a bit low on funds at the moment (waiting for it in the mail). Is there a safe, non buffer way to increase ph? or should I just wait until I make an order with foster and smitts and just throw some buffers in?
