Frequently Asked Questions: ATI Essentials Pro

There is a multitude of elements that must be kept within a specific range in order to create a successful reef tank environment. The main elements that corals need to grow include Calcium, Magnesium, and Alkalinity. ATI Essentials Pro replenishes your system with these elements and many others to ensure that your water quality is ideal for both coral health and growth.

Many 2-part dosing regimens only contain calcium, magnesium, and alkalinity, and those that have the minor and trace elements included can use as many as seven bottles. ATI Essentials Pro incorporates all of these in just two bottles. With Essentials Pro, there are no complex dosing calculations needed; simply test your Alkalinity and adjust your dosage accordingly. Most users will dose each part of the system equally.

Visit our handy calculator, add your total water volume and tank type, and select whether you will be using the product diluted or straight out of the bottle. Each tank’s needs are different, so it is critical to test your alkalinity daily and adjust your dosage accordingly until you achieve a stable dosing volume.

We have a handy calculator for that too. Simply enter your tank size, current dose, and change in alkalinity (KH) to adjust your current dosage.

No. Dosing on the two highly concentrated parts should be at least 5 minutes apart and ideally farther apart. If you add the two components simultaneously, they can react and precipitate out of the water. Always dose in a high flow area, like your sump.

There are pros and cons to each method. Diluting is less risky and more accurate; however, it will require larger containers to hold the liquid or more frequent refills. If your aquarium requires a small amount of Essentials Pro, it is best to dilute it to improve dosing accuracy. For example, if your aquarium requires 10 mL per day, ½ ml over or under dose is a substantial percentage of your daily needs. If you dilute it 5x to 50 mL per day, now being ½ ml over or under is far less critical. If, on the other hand, your aquarium requires 50 mL per day, diluting by 5x would require much larger containers to hold all the fluid without much of a safety benefit. If you dilute, it is necessary to keep a consistent dilution ratio over time.

While you can dose by hand, we highly recommend using a dosing pump to ensure steady, consistent, and accurate dosing. We also recommend that you break your dose into multiple doses throughout the day. Dosing a small amount at a time throughout the day results in more consistent water parameters. Dosing larger amounts less often will result in large swings in your water parameters.

To prevent precipitation, store the product at room temperature of 68° F or higher. Keep the bottles upright and always shake vigorously before use.

Yes. While rare, some reefs consume a disproportionate amount of one over the other. If it is needed, you can certainly dose more of one bottle.

Bottle one contains alkalinity and iodine, and bottle two contains calcium, magnesium, and trace elements.

Yes, it is still safe to use. Please just follow the instructions in our How to Get ATI Essentials Pro Back into Solution article.
