I have just bought a 20 gallon tank. A while ago, I posted a thread about a 5 gallon tank that I wanted to use. Simply put, I abandoned that project and am starting this new one. So, I have the tank up with 20 .lbs of all black gravel already set up at the bottom. I bought a master test kit for the Nitrification cycle and a separate test bottle for KH and GH. I don't know what my tap water comes out as so that is the main reason why I bought this tester, making sure these properties are maintained was my second reason. Now, this leaves me with this question. Do I test for GH/KH straight from the tap water, or do I put the tap water in the tank, add chloramine neutralizer, let it filter and cycle for a few days before testing? My goal is to find out my local water's paremeters before buying fish so that I know what to stock my tank with. This is why I haven't bought any decorations yet. Also, my tank came with Incandescent lights. Does this mean that I can't use any live plants? I want to go for a natural look.
