Advanced formula for perfect stability in SPS trays
Designed for hard coral enthusiasts, ATI Essentials SPS offers a complete solution to the specific needs of SPS aquariums. It contains all the major elements (calcium, magnesium, KH, potassium, strontium, etc.) as well as a range of trace elements (iron, iodine, zinc, cobalt, etc.) essential for the growth of the calcareous skeleton and vibrant coloration . All without the risk of excess or ionic drift.
The big plus of this version? Its 100% mineral #1 KH Complex , which maintains a stable and higher pH – a key parameter for the proper development of SPS. The #2 Calcium Complex , meanwhile, is enriched with 74,000 mg/L of calcium, and covers all the trace elements necessary for the proper metabolism of corals.
Simple and precise dosage: ideal for dosing pumps
ATI has designed this system to be easy to integrate into your routine . Both solutions are dosed in the same proportions, between 5 and 10 ml per 100 liters of water depending on the measured consumption. It is therefore perfectly compatible with a dosing pump and does not require any prior dilution .
Here is a dosage guide based on your daily consumption:
| Daily KH consumption (°dKH) | Dosage #1 KH Complex |
|---|
| 0.1 | 1 ml / 100 L |
| 0.5 | 5 ml / 100 L |
| 1 | 10 ml / 100 L |
| Daily calcium intake (mg/L) | Dosage #2 Calcium Complex |
|---|
| 1 | 1.4 ml / 100 L |
| 2.5 | 3.5 ml / 100 L |
| 5 | 7 ml / 100 L |
| 10 | 14 ml / 100 L |
A ready-to-use formula, even in winter
Because the concentration is high, crystals may form in solution #1 at low temperatures. If this happens, a 45°C water bath or a radiator is sufficient to remove them. Below 20°C, a 1:1 dilution with reverse osmosis water is recommended – for both solutions – while maintaining an equal dosage.
