We always want to go bigger... I had a 60 and I thought about a 90 for an upgrade, then a 120, then a 160 -- then I purchased a 210. Now I'm drawing diagrams on how to add a fish room off of my living room and my husband is nervous about what my plans are. This is an addicting hobby. You joined the right forum. There are lots of fantastic folks here who want to help. Welcome!
