peat

So I finally ordered some peat off eBay last week and it came today. Being the person I am and not thinking ahead, I don't know what I should put it in when I want to put it in my AC50. Pantyhose? These are pellets the size of about a pea and 1/2 a pea. A picture with a coin is below. Thanks...

I'm trying to get everything organized in my tank before I pick up the fish. One of the things I just recently thought of is lowering the pH. My water is uber hard out of the tap and want to find a reliable way to lower it. Getting an RO unit is not an option at the moment. I'm moving to Albany...
