I have posted my thoughts regarding the start of a new SPS dominated system and the possible conversion of my current tank to a Dendro/Gorg system. Below is a pic of my tank as it is now: I am quite happy with it and everything is doing well - but have lost many of my SPS colonies due to the "Creosote Incident" and are looking for some inspiration . I have also switched over to the Balling method for calcium and alkalinity supplementation and would like to start a system from scratch using this instead of the usual calcium reactor. I had problems getting the alk dialled in and had some rescession on the sps corals I had left. I am also running Prodibio on this tank and am very happy with the results I have achieved so far.
