Hello everyone. My name is Ric, I am 62 and have been an amateur in fish keeping. We started with 30 gal and now I am setting up a 125 gal tank in our family room. I am going to try to find the correct threat for a couple of questions I have, but please bare with me. I am a disabled vet and have West Nile, so I get confused easy and my concentration is bad some times, please help me with my questions.
