People have been trying for years, but there's no substitute for a peristaltic pump. I went the more expensive route with a GHL profilux as I wanted some of the extra features, but there are ways to save a few bucks without sacrificing accuracy.

You can put together a quality 2 channel setup for < $200 now. The Bulk Reef Supply peristaltic pumps have a really good reputation in the reefing community. Rig up your own dosing containers, a couple timers, and you are dosing automagically.

I've used a pair on a client tank.

They have been fairly consistent once to tweak them and fiddle with the head height and run them a few times.

Careful with backflow, make sure there is an air gap at the end of line into your tank. Also, run test runs using only water, a good timer and min settings are key.

Timers often cost more than the pump.
