    Does a Trident make all the difference?

    Recently I've been considering getting a Trident. My system is all Apex controlled, and it would be an easy (albeit, very expensive!) addition. So my question to the Trident owners is this - has it made a big difference in your success? Is it worth the cost of continued reagent purchasing...

    Build Thread Brandon's Quarantine edition 80 gallon SCA upgrade.

    Hey, long time member but I never felt I hand anything that I was particularly proud of. I've kept the same Biocube 32 for 9 years with success, but I never was able to do more with it due to the size limitations of the tank. Back in late Jan, I got the go-ahead to upgrade the tank, I still...

    Trident Owners - Do You Still Test Manually?

    Question: If you own a Trident, do you still perform manual tests with the test kits that you used prior to acquiring a Trident, such as Salifert, Hanna, Red Sea, et al. Why do you, or do you not, perform manual tests? I tried searching for threads that involve discussions about whether Trident...

    Apex with Trident - Outlet Programming Based on Test Values

    I have an Apex controller with a new Trident that I just got set up. My intention is to add a dosing system using the Bulk Reef Supply (BRS) 2 Part Doser Pumps. I'm pretty sure that I know how to program an outlet on the Apex to schedule the pump to turn on based on a time parameter (e.g. run...

    How often do you calibrate your Trident?

    The solution says it's only good for 8 hours after opening and they only give you a single bottle. I feel like calibration should be done each time any of the reagents are changed, no?

    Neptune DOS + Trident

    Hello all, First off, I am sorry if this is the wrong area, it seemed right. So, I have the Neptune Trident and recently acquired the Neptune DOS. I used to have a different dosing pump, it was dosing ESV B-Ionic 2-part in the morning. Now with Trident+DOS I see that I could use the automatic...

    Results with Alkalinity Controllers

    Hi all, I'm on the fence to get a unit be it Alkatronic, KHG etc. I've been trying to go through the threads but almost all of them talk about tuning, connectivity, and troubleshooting. I was hoping to see how things turn out after you've dialed in the unit and have very stable Alk. Do the...

    Concerning the Trident:

    I know that @Terrance brought this up in a video during the Trident launch about implementing a subscription service at some point in the future.
