ATI Essentials SPS – Set 2x10L: pH stability and performance for SPS tanks

The ATI Essentials SPS – Set 2x10L was designed for SPS-dominated marine aquariums, where stability is paramount. This ultra-concentrated liquid system provides essential elements (KH, calcium, magnesium, potassium, strontium, etc.) and a carefully measured base of trace elements daily, without drift or unnecessary accumulation. Its key advantage: a 100% inorganic KH component that helps maintain a higher and more stable pH , exactly what the most demanding SPS corals require. Ready to use, compatible with dosing pumps, and calibrated to dispense both solutions in equal quantities , this 2x10L set simplifies routines while keeping the water clean, balanced, and perfectly consistent.

  • Stabilizes pH and key parameters, ideal for sensitive and demanding SPS systems
  • Simple dosage: same volumes for #1 and #2, easy to automate
  • Ready-to-use concentrated formula, no preparation required, long-lasting yield

The family ATI Essentials: a simple solution to a real puzzle

The rangeATI® EssentialsIt was designed as a complete supplementation system, capable of adapting to the type of tank (mixed reef or SPS-dominated tank) and the level of experience, from beginner to demanding enthusiast. The foundation rests onEssentials Mixed ReefAndEssentials SPS, two highly concentrated liquid solutions designed to supportgrowth,metabolismAndcoloringCorals in a saltwater aquarium. To go further, the range then allows for finer adjustments withEssential Daily Traces A & B,Essential NitroAndEssential Phospho, in order to precisely adjust to the needs of the tank. The whole process is based on experience gained from tens of thousands of ICP analyses, with formulationscontinuously optimizedOver the years.

An SPS aquarium supplement designed for everyday stability

In a tank dominated by SPS corals, they consume quickly and they hate roller-coaster cycles. ATI Essentials SPS It therefore aims for regularity: it provides complete supplementation to support growth, , metabolism And coloring, while maintaining water close to a natural balance. Thanks to the accumulated experience of numerous ICP analyses, the formulation is designed to provide a solid base of major and trace elements, with a simple logic: to nourish the reef, without overloading it.

Two complementary containers: KH + calcium, balanced for identical dosage.

The set includes two solutions to be used together, and that's precisely where it gets clever: the concentrations have been adjusted so that #1 and #2 should be dosed in equal (or very close) quantities.. In practice, the routine becomes crystal clear: a single baseline setting, then fine-tuning based on the tank's actual consumption. The result: a more stable reef, calmer SPS corals, and less time spent juggling numbers.

#1 KH Complex – Contents & Highlights

  • Concentrate : 100,000 °dKH per 10L can (10,000 °dKH/L)
  • KH based on a 100% inorganic component (highly appreciated in SPS)
  • Key contributions: fluorine And sulfur
  • Trace elements included: iron, , iodine, , selenium
  • Desired effect: Higher and more stable pH on a daily basis

#2 Calcium Complex – content & strengths

  • Concentrate : 740,000 mg Ca per 10L container (74,000 mg/L)
  • Key contributions: bor, , bromine, , potassium, , magnesium, , strontium
  • Trace elements included: cobalt, iron, lithium, manganese, molybdenum, nickel, rubidium, vanadium, zinc
  • Objective : Ionic balance and stable water, without progressive drift

Major elements + trace elements: a complete base without unnecessary accumulation

This system ensures the coverage of major elements essential to the coral skeleton (calcium, magnesium, strontium, alkalinity…), while also providing a trace element base (iodine, iron, zinc, manganese, etc.) designed to avoid the "it accumulates and eventually spirals out of control" effect. This is precisely what we're looking for in SPS: supplementation. predictable, with clean water and parameters that stay where we want them.

Dosage guidelines: calibrate according to the actual consumption of the container

The recommended dosage is intentionally kept simple: 5 to 10 ml per 100 L per day, The solution is used as a starting point. Then, adjustments are made based on the tank's daily consumption: KH and calcium levels are measured, and the adjustments are fine-tuned to precisely compensate for what is consumed. Here are some practical guidelines, useful for starting with a solid foundation.

Ready-to-use concentrated formula: practical, clean, effective

No powders, no mixtures, no containers to prepare: everything is ready. The concentration is designed to offer good yield, and use with a dosing pump is straightforward. The tank receives the same amount every day, at the same rate, and it shows: the SPS corals appreciate consistency, and so does the aquarist.

Low temperatures: what you need to know to maintain a smooth dosage

Because the solution is concentrated, the #1 KH Complex It can crystallize when it's cold. This is simply a physical effect: the crystals disappear when the container is warmed (warm water bath around the container). 45°C or radiator). If used below 20°C, A 1:1 dilution with reverse osmosis water can be considered, also diluting #2 in the same way to maintain identical dosage volumes.

Mixed Reef or SPS: visualize the differences at a glance

The choice between Mixed Reef and SPS depends mainly on the objective of the tank: mixed reefs benefit from a formula more oriented towards "versatility" and nutrient management, while the SPS version aims for stability and pH maintenance particularly appreciated by the most demanding hard corals.

The 3 pillars for healthy corals (and how the range connects to them)

To keep a reef functioning well, everything revolves around three needs: the major elements (skeleton construction), trace elements (vitality and color) and nutrient management (overall balance, polyp extension). The idea with ATI, The aim is to offer a robust base via Essentials, and then to be able to refine as needed with targeted additions, when the tank becomes more demanding or when the aquarist wants to push the settings further.

Pillar

1. Key Elements

(calcium, KH, magnesium, strontium, etc.)

2. Trace elements

3. Nutrients
