Continuous water changes

[rockworm]

I am setting up the daily change using the Profilux Controller and their dosing pumps. Profilux makes a stand-alone dosing pump that would work. You do not need an additional pump with this one. Unfortunately, dosing pumps are not cheap. These dosers are available in 1 pump to 4 pump combinations and priced accordingly.

I like the idea of mixing 50g and have it change slowly over the course of a month.

The price for a Litermeter and remote pump or Reefiller seems like the biggest drawback unless there are some cheaper options.
