DSR Reefing (2013)

       Reefing the right way!

Welcome to the DSR Reefing historical Website!
This site was founded in 2013 and will not be updated anymore!

DSR stands for "Dutch Synthetic Reefing". This is a way of keeping a mixed reef aquarium successful without waterchanges. The DSR Method was developed by myself "GlennF" as a problem solving tool for my own 1500 liter mixed reef aquarium. No water changes and controlling essential water parameters are the basics of the DSR Method.

The DSR Method, for who?

Do you want like to take reefing one step futher than the usual anemone with a couple off clownfishes?

Do you hate water changes?

Are you struggling to get control over your tank?

If you don't have any problems doing periodic measurements and all above are answered "YES", than you should consider running DSR.
