I got Hannah Alk, Ca, and Phosphate testers for $30 used. They didn't have any reagents, but that isn't a big deal. I just used them for the first time today and I got 7.7 dkh (same as my Salifert test), 470 Ca (Salifert says 430), and .03 Phosphate (Salifert says .02). What a score.
I'm looking to get a Lubbock's fairy wrasse, McCosker, and a yellow coris wrasse for the tank. I will have to order online as I have not great options for LFS in my area.
I haven't mentioned this yet, but now that I have used the Tunze Osmolator 3 for 3 months, I can say that I absolutely love this thing. It is as reliable as my old Osmolator but without all the added wires and controller. It is super easy to set up and use.
