Need a recomedation CA reactor or 2 part dosing?

[o.c.d.]

I started with the aqua medic doser and very finicky many little adjustment and I seemed to always messing with it. I finally purcased a PM calcium reactor and I'm very happy with the purchase. Hardly touch it, once dialed in every 3 months or so I get a new tank filled and exchange for 10 bucks. I also have noticed very good and stable water params. Lots of Coraline Algae growth and my refugium produces macro about twice as fast, making nutrient export more efficient. I really would not bother with 2 part any more.
