I actually have a profilux standalone (since I didn't know I would get such a good deal on a profilux controller bundle only a few weeks later), but the unit is absolutely rock solid and easy to use.
My decision was based in part by my tank size - 28g including sump. The litermeter's minimum dose is 50ml at a time - so not only would I really have to dilute things, but also have very large containers for everything.
Instead I chose the profilux as it's cheaper per pump, and more importantly it doses a minimum of 1ml instead of 50 ml (great for dosing things like VSV, vodka, etc), and great for small volumes like my tank.
I can't wait to see your build all come together. And now I wants all gray piping and fittings too
