Hi, just joined this site. What a great group of freindly folks w/ a lot of knowledge. Had a 30 gal freshwater 12 yrs. ago and loved it. Due to work was not able to keep it up properly. Has been a goal to set up a 100 gal. tank. Now that I'm semi-retired this goal is fresh in my mind. So much has changed w/ Aquiriums from what things were then. Looks like this site is a great place to start my education. kdcon
