So after a weekend of use, I'm going to say the reefbot is pretty awesome. I'm already gaining more insight into my tank and can easily see how things I do effect the water chemistry (water changes, dosing, swapping media, etc). One thing I will say, is that I believe that there's still a place for something like an Alktronic or KH Director to work in conjunction with the reefbot. I think those solutions offer up a more cost effective alk testing solution. This would also free up another slot for another test in the reefbot. I love having the extra vials available to I can quickly swap out reagents for any test I feel like running. So far I am very happy with my purchase. We will see how the product holds up long term in terms of replacing vials, syringes, pumps, etc. It would be nice to get replacement kits available for purchase, for when the time inevitably comes.
