I have dosing pumps on several tanks and have been using the Aquamedic Twin Reef dosing pumps that come with a timing system. The unit is very well put together and the timer is great because you can dose many multiple times in one day with each dosing time programmable down to the second (most digital timers can only switch on for a minimum period of one minute which can be ok depening on the flow rate of your particular dosing pump).
I use one pump for macros and the other for micros.
The only drawback, and this can be a showstopper depending on your setup, routines and location, is that if there is power cut, the unit does not come back on automatically when power is restored. It needs to be manually started up again. I have yet to figure out why in the world it was designed like this...
So if you are away alot you need to show someone how to check if it has stopped and how to start it up again.
Or get a UPS for the thing...
