THE EZ550 REEF
T
he reef tank featured in this article is one of eight reef tanks in my home. As you can imagine, I'm a reef fanatic! In the Q1 2014 issue of RHM, I introduced the Dutch Synthetic Reefing (DSR) method and featured one of my larger mixed reefs. The DSR method is a system I researched and developed. The approach of the DSR method is unique in many ways, but it stands out because it requires no water changes. While this may sound unbelievable to some aquarists, my method is proven by the success of thriving reef tanks worldwide. Without going into too much detail in this tank feature, the success of the DSR method revolves around precise, test-based micro dosing in order to maintain complete control of essential water parameters. More information on this method can be found through the links at the end of the article.
