Hello, I'm brand new to this forum. I've been a member of Nano-Reef for a few years...though haven't really posted much. Anyways, saw the really cool R2R FB posts and loved them so much I decided to join. I've been in this hobby since January 2011. I currently have 4 mixed reef saltwater nano tanks. Though my 5 gallon does not have anything in it just yet...still cycling as it's only a month old and I'm taking it slow with that one. In my 1 1/2 year old sumpless 40 breeder I'm battling dinos currently and have been for a few months. I can keep them at bay (lights out, no water changes, minimal feedings, wet skimming, etc) but just can't seem to kick them totally. My 4 year old 14 and 29 gallon Biocubes are doing just fine. I have minimal fish (one to two per tank) in all of my tanks to keep nutrients low since I don't have any skimmers on my tanks except the 40 breeder. Anyways, I really enjoy this hobby but feel even after 4 years I know so very little. So I'm here to learn.
