Well for one I have zero knowledge when it comes to programming so a plug in and play unit is preferable for me and two I don't think your route is actually that much cheaper.
The bulkreef supply dosers are going for appx. $90.00 each, to dose CA, ALK and MG we would need three of them. On top of that the apex controller system is $500.00, so for $800.00 plus shipping you get your basics.
For $350.00 shipping included I got the triple doser, jugs to hold all the solutions, plastic airline tubing, measuring cups, ALK/CA/ALK chemicals that will last me for half a year and a one year warranty.
You do the math, I'm pretty happy with the purchase.
