Sorry to be so late answering this. We are pretty new, having been in operation for only about 5 months. We have 10 members, to date, and usually have 7-9 at our meetings. So, we are a small group, where everyone gets to say whatever they want, and get answers to any questions they have. Our members range from people just starting with a planted tank, to those of us who have been keeping such tanks for several years.
If you are in the area, please join us at our next meeting. It helps if you go to http://intplantscaping.meetup.com/11/
and join the group, so we know how many to expect at the meeting.
