The perspective above is maybe just a tad on the negative side. Anyone who is dosing or trying to manage their water chemistry will appreciate the data and graphs that a trident gives you. For me, the newness of my Apex hasn’t worn off, I reefed for over a decade without one and only about 4 months with one, that said, I’m in no rush to go back. Can you find cheaper gear to do everything an Apex can do? Yes of course you can. Can you find apps or create spreadsheets to compile and graph everything that an Apex can? Yes for sure. Would I spend the time pulling data from a dozen different wifi power bars, monitors, test its, lighting controllers, etc. and compile it into one place, graph it, and identify all the trends? Nope, I’m too lazy for that. The power is having it all in one place, all done automatically. Even if you don’t have a trident and DOS, which I don’t yet, you can enter your test results directly (I know, data entry I just said I wouldn’t do) and have them tracked nicely. It will remind you when to change your water, change your T5 bulbs, tell you when your pumps are getting dirty (change in power draw), and a slew of other things.
I think you have to be the right kind of reefer to benefit from an Apex. If you are looking for something to turn things off and on and nothing more, save your money, there are cheaper ways. Certainly if you are going to “do nothing” with the data it spits out then an Apex isn’t for you. If you want to build a dataset on your tank parameters, power draw, maintenance events, etc. Then an Apex might be in your wheelhouse and worth the expense. Seriously consider what you want to accomplish with it before you dive in though, an Apex and all the modules you might want couldn’t very well double the hardware cost of your build.
