Hey guys thought I would ask what your opinions on using a Versa over FX-STP, I currently use a Kamoer on my 120's calcium reactor but I was curious if anyone has had success with using Versas. I personally love the Kamoer but I am setting up another tank and would be up to try something different. I do remember a couple years ago that people were having issues with Mobius and the constant dose mode, I use the Versa as traditional dosing pumps currently.
