Dosing a large reef tank help needed.

Hi every one Im currently in the process of starting a 250 gal sps reef aquarium ,I have a few questions on dosing pumps witch ones are recommend for 2 part,I was thinking maybe going with BRS pumps and setting them up to my reef keeper I've also seen some instructions to make a DIY system with 2 Toms aqua lifters and some small check valves.Any advice would be great.

Why not just go with kalkwasser and run one aqualifter pump on an ATO switch?
I used to do 2 part but the BRS kalk is soooooo much easier.
