Hi to all. Just joined the community, and already have found tons of info. I am Both old and new to fish keeping. When i was a young man my dad had 35 tanks, and raised fish for the local shops. i was around 10. We use well water so we had little trouble. Now i am 55 and starting a 60 hex, and i am overwhelmed by the science and information that i read. I want to thank you ahead of time as i know i will ask a ton of dumb questions.
