Hi everyone, I'm a 61 y.o. woman and am retired. I have recently taken interest in starting up my old hobby again, and since I have not had aquarium since I was in my 30's, I think I qualify as "newbie" ...at least I am new to the size tank I recently purchased; I have not had tanks over 20 gallons before. I Have been looking to join a forum now that I am setting up a new 50 gallon aquarium, and given the fact that I have run into a problem just this morning, I joined up here because right now I do need advice! So, I will now go search for the appropriate place to post my questions and pictures of my concerns.
