Hi Jess, If you wan to make something to raise your buffer do this:
Take a small box of baking soda and spread it out on a cookie sheet. Then bake it in your oven on 350 degrees for 2 hours.

You have now just made washing soda which raises the PH when added to your tank, make sure you test the washing soda first by adding it to a water sample from your tank. Only a small amount at a time is needed to raise your ph and it is only meant as a temperary solution. Remember this, 6 parts baking soda to 1 part washing soda becomes a neutral mixture. But added in this ratio can buffer your alkality without affecting your PH.
