I looked into the reefbot but I think the cost of the Trident and the reagents will pay for itself in time & energy (I hope). From what I understand, The Trident will test Alk, CA, and mag while the reefbot will do the same but you will need to purchase individual tests kits to supply the reefbot. The other alternative would be the KH director but that will only monitor and maintain Alk. the way I see it:
Reefbot - Maybe more costly to run over time and will not filter information into your Apex ( guessing here) but you can also run various tests outside of the big 3
KH Director - Only manages KH but does a pretty good job from the reviews I have read ( $800)
Trident - Testing big three with 2 months worth of standard testing @ $40 (4 alk tests a day and CA and Mag 2x a day)
I have no problem being a guinea pig and testing the trident out for myself--- others on the forum have said they may not rely on it right away. Most likely I will not automate any sort of dosing through Apex because of the tests on the trident. I will more than likely have it just "report" its findings which will allow me to make a more informed decision on dosing. Plus, I will be running a calcium reactor with it so that may prove to be my only option since it is a dastaco and i cannot run it nonstop as it is oversized for my current system.
Keep posting yall!!! lets get to 2k!!!
