Selling my Alkatronic (Updated Version) as I never found the time to utilize it to its potential. I took it out of the box and went through the setup protocols but never ended up using it, so my loss is your gain on this essentially brand-new system. Probe has been out of water so I would...

Turns out that you need to change the needles used by the Mastertronic every 4 weeks and today I saw that Coralvue started selling a pack of 6 needles and 4 syringes for $25!!! I'm used to big markups in the aquarium trade but I think this is huge considering you can buy a 100 pack of syringes...

Mastertronic Honest review! Initial setup: Got my package from DHL, the box was slightly damaged but it hadn’t punctured the soft box inside so I continued to unbox it - new notification in Focustronic owners group in Facebook: Open the box carefully because the vials are exactly in middle...

I was surprised there wasn't a post about this already, but we finally have some more details about the Mastertronic! I'm a big fan of my Alkatronic and really want a auto tester for Nitrate and Phosphate, so this is def on my radar. It'll be interesting to see how they price it relative to...
