Hi all, found out about this site at Macna 2010. Always nice to find new forums to give and get more info. i have been keeping reef tanks for 30 years. Currently have a 120 that i am trying a hybrid reef/seagrass tank. Just started by converting my 120 reef into this. Still in infancy stage and waiting for seagrass to take hold. Glad to be here and look forward to useful and accurate exchange of info.:smile:
