I got a Neptune Trident (ACM) two months ago to test for me and have it paired with the Dos to automate my dosing. Up until this point, it has worked like a dream. My levels had been pegged and everything was running smoothly.... until it wasn't. I noticed an Alk test result way above where it...
Neptune Trident for sale after tank teardown. Alk testing was working and Calcium/Magnesium were spotty. It could be sent in for refurbish or used for parts as needed. Includes the box but I don't have the foam pieces. I'll back well in bubble wrap for shipping. Also includes box of reagent...

I am putting up for your consideration my 2 Neptune Tridents.
The first one is probably close to 4 years old. Ran great with no problems. Ran out for about 18 to 24 months. I remember it did well past the original use life before cleaning.
Instead of just sending this one off, I chose...
Bought these about a year ago for a new tank setup, but never had time to set up due to unexpected pregnancy. Both are new in box, never used and have been sitting in our closet (dos box got a bit smushed but everything inside is fine)! We need space for our baby now! Located out of Palm Beach...

Well it all started with a trip to the city to find my first dosing system, for my 40g breeder. The LFS had a redsea reefdose 4 in stock so I decided to make the long 1hr drive... plus I love going to brick and mortar stores!! As I was walking out I spotted a Eshopps Mariner 100 (the...

I am having issues trusting the numbers I am getting from my trident. I tried first calibrating with the old calibration fluid that was given to me and then recalibrated using fresh saltwater mix. I plan on recalibrating today using tank water that is tested w Hannah / Salifert and averaged out...
Hey all,
I have an like brand new Neptune Trident for sale. I used this for 3 weeks to make sure the parameters were correct. I had a Trident before this one and it was always off. This one is perfect and was very consistent.
As you can see in the photos, it's basically new. No salt in the...
Neptune Trident from their replacement program that was used for a few months. It works fine now, but I just realized it’s not worth wasting money on reagents with an LPS tank that’s pretty stable and doesn’t need it. Price is shipped without reagents and is firm.
This was shipped to me by Neptune directly as a replacement for my unit that flailed, it has not been opened and is still sealed. Had to wait a while for this and I've honestly gotten used to testing manually so I see no need to hook this one up. During the wait I also purchased 6 months of...
As the title says.
Below is the timeline.
I sent my @NeptunePaul Trident in for servicing on December 8th 2023. They received it on December 12th
On January 24th 2024 (well over a month after sending it in), I sent an email inquiring about the status of my trident. Neptune responded that day...

I’ve been running 2 Tridents for a few years now with very few issues aside from clearing the occasional clog.
Recently, one of my Tridents developed a clog in the black hub which I cleared (I’m not getting any test failures now).
The issue now is that my Alk readings are 11.9 when I’m...
