Rubidium in marine aquariums: a vital microelement often overlooked
Rubidium is a little-known element in the aquarium hobby, but its role is not insignificant. It supports certain cellular functions in corals, particularly soft corals such as discosoma, ricordea, and bounce mushroom anemones . When it is absent or present in too low a quantity, we can observe a progressive degeneration of these tissues, fading colors, or even a slowdown in growth.
However, the majority of sea salts available on the market are low in rubidium, often for cost reasons. Because this alkali metal is expensive, it is sometimes completely absent from certain generic supplement formulas. With ATI ICP Rubidium , you have a targeted solution to effectively correct this deficiency and offer your corals an environment closer to natural seawater.
A concentrated solution, easy to dose daily
The 150 ml bottle contains 75,000 µg of pure rubidium , enough for months of treatment. Each milliliter added to 100 liters of water increases the rubidium level by 5 µg/l. The maximum recommended dose per day is 5 ml/100 L , or an intake of 25 µg/l. Thanks to this well-calibrated concentration, it is easy to adjust the level of the missing element without excess or unwanted side effects.
| Increase target | Recommended dosage |
|---|
| +5 µg/l of rubidium in 100 L | 1 ml |
| Maximum daily increase (25 µg/l) | 5 ml / 100 L |
| Total rubidium contained in the vial | 75,000 µg |
