TRIDENT-I

A key ingredient to a great reef aquarium is maintaining proper levels of Alkalinity, Calcium, and Magnesium.

The Trident is an automated testing system that regularly tests alkalinity, calcium, and magnesium in your saltwater aquarium — and then communicates this information to your Apex so you can get alerts, and change your dosing. When combined with the DOS (available separately) it creates a fully automated system for the proper dosing of supplements, maintaining them at consistent levels.

FINALLY, TOSS ALL THOSE TEST KITS!
Syringes, vials, colors, endpoints, expiration dates — now a thing of the past for Alkalinity, Calcium, and Magnesium. Now, with zero effort, you get up to date values for Alkalinity, Calcium, and Magnesium — anywhere in the world!

HOW IT WORKS
The Trident is a self contained automatic titration colorimeter. That’s quite a mouthful, for sure, so let’s state it as simply as we can. The Trident is basically automating what you (and top scientists) do already when you test your water, that is, perform a color changing titration and interpret the results.

On a scheduled basis the Trident carefully mixes its reagents with a small amount of sample water from your aquarium. While doing this, it is measuring (titrating with a precision peristaltic pump) the amounts of each that are necessary to reach an expected color change (determined by the electronic colorimeter). When it finishes the titration, it sends this sample/reagent fluid to your waste container. It then interprets the results of that test and logs the value into your Apex.

EASY PLUG AND PLAY SET UP
From the box to testing in under 15 minutes! Unlike other testing systems, there are no reagents to mix, tubes to cut, or pumps or probes to calibrate. Simply plug in one cable, two tubes, and run the setup task on the Apex Fusion mobile app — it holds your hand through the installation with helpful videos along the way.

CONSISTENCY AND PRECISION, TEST AFTER TEST
The Trident tests with a precision of +/- 0.05 dKh for Alkalinity and 15ppm for Calcium and Magnesium. This is better than humans can do consistently with every hobby-grade test kit on the market.

UNDERSTAND YOUR AQUARIUM LIKE NEVER BEFORE
When you start getting the regular data coming in from the Trident you will be amazed at the things you can see happening. The daily light cycle swing on calcium carbonate uptake. A salinity drop by watching magnesium. An out of sync dosing of calcium. This increased understanding ultimately helps you maintain a better, more successful reef.

OUT OF RANGE ACTIONS AND ALERTS
You can set up your Apex to alert you, or take immediate action(s) when a parameter falls outside of the safe zone you specify. As just one example, you might be dosing an Alkalinity solution and a misconfiguration could lead to overdosing of your tank. The Trident will catch that, alert you, and give you more time to make that correction before its too late and to save your aquarium. The data from the Trident can also be used to turn on and off other devices (like dosers or solenoids) to protect your tank even more.

AUTOMATIC DOSING CONTROL – ULTIMATE STABILITY
The more stable you maintain proper levels of Alkalinity, Calcium, and Magnesium, the better your corals will grow and thrive. But coral uptake of these supplements often changes and requires us not only to perform more testing, but also seems to put us in a never-ending state of adjusting our dosing levels.

The Trident, when paired up with one or more of our DŌS systems solves this problem with Automatic Dosing Control (ADC)

When configured on the Apex, ADC will take the results it receives from the Trident and use them to gradually turn up or down the amount of additive your DŌS delivers. But, don’t worry, we have built this feature with safety in mind. With ADC you set your target value and your starting dosing amount and ADC will only tune that dosing level +/-35%. If it takes more than that amount of dosing to keep your aquarium at your target value, then the Apex will stop ADC, revert to your starting dosing amount, and alert you that you need to manually adjust your dosing level. Then, ADC can be reenabled and it will continue to guide your DŌS so that it keeps you as close to your target value as possible.

It is possible to use ADC for all three tests – Alkalinity, Calcium, and Magnesium. You can also use one test value to adjust up or down more than one additive delivered by the DŌS (i.e. Triton system).

SIMPLE, INFREQUENT REAGENT CHANGES
When using the default testing schedule of four (4) alkalinity, two (2) calcium, and two (2) magnesium tests a day, the reagent stored inside the Apex will last a full month. And adding new reagent is super simple — just slide out the drawer, remove the old bottle(s), and replace them with new ones. If you desire, you can also run a calibration with the included calibration standard.

REASONABLY PRICED REAGENTS
The cost of reagents and recurring cost is a valid concern for a hobbyist considering the test kit or automated system – and we designed the Trident with that in mind – keeping those costs as low as possible. Reagent comes in 2-month kits (based on the default testing schedule of 4-Alk/2-Ca/2-Mg per day). These kits include two bottles of Reagent A (changed every month), one each of Reagent B and C (changed every two months), and one bottle of our calibration seawater sample. The reagent kit has at least 240 alkalinity tests and 120 tests each of Calcium and Magnesium.

SUPER-QUIET
You will hear the Trident operate from time to time if you listen closely or you have a super-quiet room. And, as compared to other automated testing systems, it is several dB quieter. While inside your cabinet along with your other equipment, you will likely never even hear it.

HIGHLIGHTED FEATURES:
Automatically tests seawater for Alkalinity, Calcium, and Magnesium
Up to 24 Alkalinity tests per day with +/-.05 dKh precision
Up to 12 Calcium tests per day with +/-15 ppm precision
Up to 12 Magnesium tests per day with +/-15 ppm precision
~7.9ml sample water used per parameter tested
~7 minutes testing time per parameter tested
Up to one month of testing before reagents need changing based on base level testing of 4-Alk, 2-Ca, 2-Mg per day.

When combined with DŌS system (available seperately), the data from Trident can be used to automatically raise or lower the amount of additives dosed as necessary to maintain stability at user set point.

Good looking toy that has held up well
Style: Coyote, Style: Coyote
Very durable toy that our little dog especially loves. It's the perfect size for a small dog and she doesn't destroy toys anyway so it's been great. It does feel very durable though and would take our chewer a little while to get to it as well. I'm not sure it looks like a coyote but the dogs don't seem to mind. It's an attractive toy that looks great and is constructed well so it's not like a slobbery mess when left out. Good value for the money and would make a great gift because it looks higher quality than most toys.

May be ballistic nylon, but the seams are flimsy.
Style: Gator, Style: Gator
I really wanted my pup to like this toy because it looks great and feels solid at first. The design is fun, the material seems tough, and it definitely gives the impression that it can handle some rough play. Unfortunately, that didn’t turn out to be the case at all. After just about 5 minutes of play, the top seam split open and stuffing started coming out. This wasn’t even extreme chewing, just normal play, and it failed almost immediately. As you can see in the photos, the tear happened right along the top seam, which is exactly where you’d expect a toy to be reinforced. Once it opened up, the toy was essentially done. For something marketed as ballistic nylon, this was really disappointing. It might be fine for very gentle dogs, but if your dog has even moderate chewing habits, this likely won’t last. Based on my experience, I wouldn’t recommend it. especially at 19.99 which is the price at time of my review, I feel it does not offer good value for money.

A Surprisingly Tough Favorite for All Four of My Dogs
Style: Armadillo, Style: Armadillo
I wasn’t sure what to expect from the Hound 2.0 stuffed armadillo toy, but it has been a total hit in my house. Neither the dogs nor I have managed to find the squeaker yet—so it’s either missing or extremely well hidden—but honestly, the dogs don’t seem to care at all. They love this thing. I have four dogs ranging from a 22 lb Boston Terrier to an 85 lb pitbull, plus two medium Blue Heelers in between, and this toy has been thoroughly tested by every size and play style. I was a little unsure whether they’d like the harder “shell” portion of the armadillo, but they actually love it. It gives the toy a unique texture and makes it feel more durable. Before this, I knew nothing about the Hound 2.0 brand, but I’m a fan now. My little Boston Terrier is notorious for ripping every toy he touches, and this armadillo has stood up to him like a champ. The tag said it was made for outdoor play, wrestling, and chewing—and that’s absolutely true. I haven’t taken it outside yet, but inside it has survived rough play from all four dogs and still looks brand new. I also love that each toy in this line is a different animal with the hard parts in different places. It makes them feel unique instead of just the same toy in different shapes. I’ll definitely be buying more of these. If you have a pup—big, small, or anywhere in between—I’d recommend giving this toy a try. It’s been a winner in my multi‑dog home.

Unique armadillo design
Style: Armadillo
I love the look of this armadillo toy. The flexible rubber shell gives it a spiky texture. It has reinforced nylon seams and printed eyes. The feet allow the toy to stand on its own, daring dogs to come knock it over. With a body length of 12" and standing 5" tall, the toy is of good size for even larger dogs, but it intimidated my 8lb yorkie mix. She found the hard shell and spikes off-putting and not fun. The toy is supposed to squeak, but either mine was broken or buried too deep to be useful. This was disappointing because I think a squeak would have helped my pup engage with the toy because she can't resist a noisy toy. I'd recommend this armadillo for larger dogs than my tiny pup. It seems durable with that rubber shell around the body.

A hound's dream toy.
Size: Small, Style: Mallard Duck
I bought this for our "grandson"--a happy go lucky beagle--to play with while we were dogsitting. It took a while to motivate him to play with it, but eventually he caved... and then promptly proceeded to tear its insides out! I took a photo and sent it to my son, and he remarked, "Wow, it has been a long time since he played with a toy like that." So even an old hound past his prime enjoyed this toy. As for quality, this is a very well made toy. Yes, it's true that the dog ripped it to shreds, but that'll happen to any toy if the dog is determined enough. I was happy he enjoyed it. He also has two loofa dog toys here that he hardly ever touches, but this duck toy was too much for him to resist. My only suggestion is to supervise your dog while he plays with this. Besides the inner stuffing, the toy has a fuzzy surface to it, and you don't want him chewing a bunch of fuzz if he tears some out, as dogs are apt to do. Other than that, GREAT DOG TOY!
