Hello! I'm new to this forum. I'm not new to aquariums but It seems I have forgotten a lot about them. After many years I just bought a 20 gallon starter tank from Walmart. I remembered that this hobby was expensive but the enjoyment out weighs the expense. My tank is in the beginning of the cycling process and I'm trying to be patient as I buy supplies and upgrade my tank with new lighting and so forth. I look forward to learning from many of you.
