Regardless of the programming on any output, if you move the slider to ON or OFF, it should respond. The programming is only followed if you have it set to AUTO.

You tried all of the above?

OK, the EB832 should not have any limitations on that doser. If a particular output is misbehaving, then I would take the following actions in this sequence to rule out possible problems: 1. Update the EB832 module software (even if it currently reports the software version is OK). 2. Reboot the Apex. 3. Carefully inspect each AquaBus port and every AquaBus cable end for any corrosion. Corrosion on single connector (even an unused port) can wreak havoc on Apex communications across all the modules in unexpected ways.

Programming on one output cannot block another output from being manually or programmatically controlled. Is this an EB832, or the older EB8? The older EB8 uses TRIAC solid-state switches on outputs 1-3 and 5-7. Only output 4 and 8 use mechanical relays (the ones that make an audible "click" when they turn on and off). Due to a limitation on TRIAC switches, they can have a problem controlling devices which have very low power draw (under 4-5 watts) so Neptune always recommends connecting low-power devices to output 4 or 8 don't suffer from that limitation. The newer EB832 uses mechanical relays for all 8 outputs, so it doesn't have this problem with low-power devices.

I just ran across a photo from May 2018, and realized it's the original photo for my avatar: Any of you have good back stories of your avatars?

This was my first ever attempt at cooking a Thanksgiving dinner on my own! My wife and I are enjoying a great getaway at a beach rental house in Yachats with close friends in our COVID bubble, eating delicious food, drinking excellent wine, and sharing lots of laughs. Hope all of you are having the best Thanksgiving possible given the limitations we're faced with. 🙂

Define "Pacific". That could range from cold waters in Alaska to warm waters in Baja. Even if you acclimate them, I can't imagine a species expecting 50 F water temps to survive in a 78 F aquarium.

Nice setup, and great colors! I like your cabinet idea.

Unfortunately the Trident water sample tube is only 5 feet long and cannot be extended. The length of the tube impacts testing results.

I just recorded a video to show each of the DOS speeds so you can get an idea of the noise levels:

One of my non-reefing friends pointed me to this: https://www.newsweek.com/sea-urchin-hats-saltwater-aquarium-cowboy-viking-top-hat-3d-printing-1500500

The most common cause of salinity probe problems is air bubbles trapped inside the tube. I've had great success with my salinity probe by mounting it upside down so air bubbles just float up and out of the tube without being trapped. I also calibrate the probe upside down by placing the calibration solution and probe tip inside a probe storage bottle, then inverting it: https://www.bulkreefsupply.com/brs-ph-orp-probe-tip-soaker-bottle.html When using the John Guest fittings, did you cut off the tip of the DOS fitting conical section? If not, it obstructs the push-connect fitting from sealing properly. I just use a razor knife to slice off the gray conical tip, then thread the John Guest fitting firmly into place. I've had zero problems with a tight seal.

Since you've made some significant Apex programming changes, don't forget to save a new backup of your configuration. Instructions here: https://www.reef2reef.com/threads/apex-users-public-service-announcement.622847/

Or returns them infested with red bugs??? (guilty...)

I've been an Apex user since early 2018, and a Trident owner since the initial launch day. I've had great success with my entire Apex setup, including the Trident. If you're not aware, I'm the resident Apex guru and published many articles on Apex programming and usage: https://www.reef2reef.com/ams/authors/suncrestreef.93940/ I also have a detailed write-up of my Trident experience including Trident Controlled Dosing: https://www.reef2reef.com/threads/trident-hands-on.596716/ In my opinion, most of the negative reviews are due to user error or misunderstanding how to properly configure the modules. That's the main reason I wrote all the tutorials. I have one DOS running auto water changes daily, and another DOS supplying 2-part controlled by the Trident. Both have worked well. I did replace the stock tubing connectors with John Guest push-connect fittings which eliminated the occasional problem of air in the tubing:

Wow, it all seemed so simple when you first posted the question. I still have no idea why the OSC directly on the WXM outputs won't work properly, but glad to hear it works with the virtual outputs. Unfortunately I don't have a WXM or MP's to further test and investigate on my own.

Yes, I've seen this error several times today. Usually I just reload the page and that works.

Do you know for sure if the OSC commands are functioning at all, or are they just leaving the powerheads on at all times? You could try moving the OSC into a virtual output, then control the MPs by the virtual output state: [vFront] OSC 000:00/005:00/007:00 Then ON [vBack] OSC 007:00/005:00/000:00 Then ON [MP60_FRONT] Set OFF If Output vFront = ON Then MP-Constant [MP60_BACK] Set OFF If Output vBack = ON Then MP-Constant

OK, I'm stumped. I'd recommend rebooting your Apex because something just doesn't seem right.

This should NOT make any difference, but since the situation doesn't make sense, humor me... Change the graphical schedule to only run from 00:00 to 00:01. The OSC should always override the schedule, but that's the only possible reason I can think of for your issue.
