Yeah, about three years doing saltwater and never really took the leap into any kind of controller. Again my main focus is to get hourly updates on Alk, Cal and Mag and go from there. I recently started to focus more on SPS.
I apologize for that presumption that you have the Apex and are looking for Trident as an add-on. So, here's a wordy but factual introduction, from a current user, if you are looking for one.
To monitor your Calc, Mg and Alk you will need the two systems from Neptune (that's the company's name) -
- the Apex
- the Trident
The
Apex (think of it like the brains) is the core system. Setting up the Apex is a hell-in-a-handbasket!! Trident not so much.
Apex comprises of a multipin equipment-controller for heaters, powerheads, skimmer, lights etc. (called the Apex Controller), and a networked-monitor so that you can monitor pH, Temp, Salinity and ORP (a measure of oxidation power of your tank's water) using your smart phone web-browser etc. (called the Apex Fusion). These two in combination form the core-system and does about 60% of all required automation in a Reef Tank. Without the Apex, none of the other add-ons (including Trident) will work - remember "Brains". Once the Brains (Apex) is installed, you can add many, many limbs (add-ons) to the brain.
Trident is one of the limbs (add on) of the Apex system, which monitors Calc, Mg and Alkalinity.
Neptune devices do not measures Nitrates and Phosphates unfortunately, and they do not work with third-party probes. So, for Nitrates and Phosphates you have to rely on test kits, Hanna etc.
There is a step-down version of Apex called Apex EL, which may also work for this purpose - but don't quote me on that. On the rest of my post, you can quote me
Neptune's hardware is decent, but its software is glitchy (works about 99% of the time - but irritates the hell outa you on that 1% case). In Neptune's defense, their support is really, really solid. Thank God for small-blessings.
There are alternative setups to Neptune's Apex/Trident like GHL ... but I am clueless about the ins-and-outs of those. Search within today's R2R posts regarding a reefer getting rid of his Neptune Systems in favor of GHL (you may actually get a good deal from him) - and he will likely let you know why the grapes soured for him. Here's the link to his thread -

Feel free to message this forum at any time you have a Neptune setup issue. There are a plenty of good samaritans here who will provide good guidance. If we have had the Apex/Neptune we likely would have encountered the issue that you are experiencing.
Good luck, sir!
