Maximal dosing 6ml / 100l About (DSR) Dutch Synthetic Reefing Founded by Glenn Fong, the DSR method is a simple method of keeping a thriving reef aquarium without the need for water changes. By adding major and minor trace elements through the EZ DSR method, spectacular results can be achieved with less maintenance. With the DSR Method it is possible to establish a stable and controlled reef environment. Its an all-in-one reef aquarium maintenance solution. The costs of running the DSR method are a fraction of reef salt needed for regular water changes. You learn to understand the way things work and you get more control of the biochemical processes in your reef aquarium. The EZ-DSR program is an easy to use method with 4 instant dosing solutions. The EZ-Buffer, EZ Calcium and EZ Trace can be initiated at a fixed ratio of 5:1:0.5. The EZ-Carbon solution decreases PO4 and NO3 very efficiently and is dosed according to your phosphate and nitrate levels. The 4 solutions are available in 500mL, 1000mL, 5000mL and 10000mL sizes. Due to the ratios of how the trace minerals are added, it is recommended to buy a larger size of EZ Buffer than the other additives.
