For about 3.5 years, I've run a small frag tank tied into the main reef to hold small coral fragments, interesting NPS corals and other recent acquisitions.  It's badly in need of being replaced. Not only is it full with corals from end to end that have grown into serious colonies, but there's an onging algae issue that I'm attributing to the aged light fixture hanging above.  A new one will replace it, and it will be stand alone with all the filtration that entails.  Each day I see this mess and I can't wait to replace it, but I need the time to build... but customers are waiting for their orders so I have to put them first.  Hopefully in the next couple of months I'll find the time to get this done.
