I've seen your tank and while you're lightly stocked on corals unless your planning on stuffing your tank with full of sps a doser will work fine, just order the 5g pails from brs and you're good to go.

I have 2 jebao dosers and they are hassle free calibrate it and off you go.

I've also owned a vertex doser before aswell easy to set up and touch screen display is awesome but clunky size is a downside.

Also a ca reactor I think initially costs a lot, like over $1k once you factor in the reactor a 20lb tank, selenoid and ph controller....

A doser like the jebao is about $100, the bulk chems are $400 but that can last you atleast 4-5 years.
