ATI Labs - Selenium 150 ml is an ultra-pure solution designed to restore selenium balance in reef aquariums. Even in very small amounts, this trace element is crucial for the health of corals, especially those exposed to high light intensity . Indeed, selenium is involved in the production of certain protective proteins that act as natural antioxidants. When it is lacking, corals become more susceptible to oxidative stress, which can lead to general weakening. Thanks to its precise dosage and its formulation from the German ATI laboratories, this supplement allows for reliable and safe adjustment of selenium, while being compatible with ICP analyses.
Selenium is a trace mineral often overlooked in micronutrient management, but its role is crucial for corals living under high light intensity. It participates in the formation of antioxidant proteins that help coral tissue defend itself against cellular damage caused by UV rays and excess light. When selenium levels become too low, corals become more vulnerable, their light tolerance decreases, and their vitality suffers.
There are many causes of a deficiency: low concentration in sea salts , absence in certain reef supplement formulas, or even too generic trace element mixtures. ATI has designed this solution to meet this specific need , with exceptional purity and a concentration perfectly suited to aquarium use.
ATI Selenium Solution contains 7,500 µg per 150 ml bottle . Each milliliter increases the selenium concentration by 0.5 µg/l per 100 liters of water. This is also the maximum recommended daily dose, which allows for optimal stability without the risk of overdose . The product is therefore particularly suitable for aquarists following an ICP analysis protocol or looking to refine the final details of their supplementation.
| Dosage target | Recommended quantity |
|---|---|
| Increase by 0.5 µg/l per 100 L | 1 ml |
| Maximum recommended daily dosage | 1 ml / 100 L |
| Total amount of selenium per bottle | 7,500 µg |
Like all elements in the ATI ICP Elements range, selenium is manufactured in Germany, with highly purified raw materials , in compliance with the strictest European standards (CLP regulation EC n°1272/2008). Each batch is precisely controlled by the ATI laboratory, guaranteeing full traceability and complete transparency on the selenium content indicated on the label. This supplement is classified for informed users, those who master individualized supplementation with rigor and precision.
This supplement contains concentrated Sulfur.
10 ml of product increases the fluoride level by 4 mg/l (ppm) in 100 liters of water.
The recommended level of sulfur in aquarium water is 740 to 990 mg/l.
