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 colour changing titration and interpret the results.\u003c\/p\u003e\n\u003cp\u003eOn 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 colour 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEasy Plug \u0026amp; Play Setup\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFrom 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConsistency \u0026amp; Precision\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUnderstand Your Reef Tank Like Never Before\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstant Alerts \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYou 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUltimate Stability with the Neptune DŌS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe Trident, when paired up with one or more of our DŌS systems solves this problem with Automatic Dosing Control (ADC)\u003c\/p\u003e\n\u003cp\u003eWhen configured on the Apex, ADC will take the results it receives from the Trident and uses 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 re-enabled and it will continue to guide your DŌS so that it keeps you as close to your target value as possible.\u003c\/p\u003e\n\u003cp\u003eIt 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).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSimple Reagent Changes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen 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 session with the included calibration standard.\u003c\/p\u003e\n\u003cp\u003eThe cost of reagents and the 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. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUltra-Quiet Testing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYou will hear the Trident operate from time to time if you listen closely or you have a super-quiet room.

This helps the Trident \"learn\" the specific conditions of your installation (e.g., sample line head height).\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eReagent Batch Consistency:\u003c\/strong\u003e Each 2-month (and typically 6-month) Trident Reagent Kit from Neptune Systems includes a fresh bottle of calibration solution. This is because Neptune Systems strives for consistency across batches, and the calibration solution helps the Trident to be calibrated to that specific batch of reagents.\u003cbr\u003eTroubleshooting\/Accuracy Checks: If you suspect your Trident readings are drifting or are significantly off compared to manual test kits or ICP tests, a calibration can help verify or correct its performance.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eAfter Major Maintenance:\u003c\/strong\u003e While not strictly required, if you perform significant maintenance on the Trident's internal plumbing (e.g., replacing sample or waste lines, or the DIY service kit), a calibration can help re-establish optimal performance.\u003cbr\u003eImportant Notes about Trident Calibration:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded with Reagents: \u003c\/strong\u003eYou generally purchase the Trident Calibration Solution as part of the Trident Reagent Kit (2-month or 6-month supply). You can sometimes find it sold separately by retailers if you need an extra bottle without buying a full reagent kit.\u003cbr\u003eNot a Replacement for Reagents: The calibration solution is not a reagent itself. It's solely for calibration.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eSingle Use:\u003c\/strong\u003e Once a bottle of calibration solution is opened and used for a calibration, Neptune Systems states that it should be considered used up and disposed of. It will not hold its stated values for long once exposed to air.\u003cbr\u003eSpecific Process: The calibration process involves placing the Trident's sample line into the calibration solution and running a specific \"Trident Calibration\" task through Apex Fusion. The Trident will draw the solution, perform its internal tests, and adjust its readings accordingly. This process can take around 40-70 minutes.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFrequency:\u003c\/strong\u003e Neptune Systems' general recommendation is to calibrate the Trident with each new batch of reagents. So, if you're using 2-month reagent kits, you'd calibrate roughly every two months. Many users also compare their Trident readings to trusted manual test kits (e.g., Hanna checkers) or ICP tests to decide if more frequent calibration is needed or if an offset should be applied in Apex Fusion.\u003cbr\u003eWhere to buy Trident Calibration Solution in Australia:\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Neptune","offers":[{"title":"Default Title","offer_id":46913939144874,"sku":"NPTRI-CAL","price":24.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0325\/1250\/7948\/files\/NeptuneSystemsTridentCalibrationSolution.jpg?v=1750305566"},{"product_id":"neptune-systems-1-aquabus-cable-m-m","title":"Neptune Systems 1' AquaBus Cable (M\/M)","description":"\u003ch5\u003e\u003cspan\u003eDescription:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cdiv\u003e\n\u003cdiv dir=\"ltr\" id=\"model-response-message-contentr_c8c26d085aab5105\" class=\"markdown markdown-main-panel enable-updated-hr-color\"\u003e\n\u003cdiv dir=\"ltr\" id=\"model-response-message-contentr_f1efd824b07ee691\" class=\"markdown markdown-main-panel enable-updated-hr-color\"\u003e\n\u003cdiv class=\"fusion-text fusion-text-10\"\u003e\n\u003cp\u003eAquabus is the communication link between your Apex and most of our modules.  The cable itself looks just like a USB cable, but it is not to be confused with a USB cable.  Connecting a computer or USB accessory, like your phone, to the Aquabus will likely result in damage to that accessory and possibly to the Apex.\u003c\/p\u003e\n\u003cp\u003eThere are two types of Aquabus cables.  One is for connecting Neptune Systems’ modules together and the other type is an extension cable.
