Rubidium, 120 mL, Highly Concentrated Trace Element Supplement for Reef Aquarium

Rubidium Supplement – Advanced Trace Element for Reef Balance Includes a dosing dropper! Fine-tune your reef with our high-purity Rubidium supplement. Though not often spotlighted, Rubidium is naturally present in seawater and plays a subtle but important role in maintaining ionic balance and supporting coral physiology—especially in complex SPS systems. Key Benefits: Helps maintain natural ionic ratios in reef systems Supports coral tissue health and metabolic function Enhances stability in trace element profiles Ideal for advanced aquarists seeking complete seawater replication Rubidium is easily stripped out by filtration and protein skimming. Regular dosing helps ensure even the most overlooked trace elements remain in balance. DIRECTIONS: Before dosing product, an ICP test should be completed to assess current tank trace element levels and target levels. See dosing calculation below to obtain the dosing amount for your tank based on the current and target levels. Pick a dosing method (see suggested methods below) and dose accordingly. Dosing should occur in high flow areas, and can be done over a period of time (recommended). Complete another ICP test in a month to understand trace element depletion levels in your tank and determine how much you should dose to maintain trace levels. DOSING CALCULATION 1mL will raise rubidium levels 0.40 micrograms in a 100 gallon tank. To adjust for your tank size, you can use the following formula: Dose (mL) = Desired Increase (µg/L) × Tank Volume (gal) Product Strength (µg/L per mL in 100 gal) × 100 Where: Tank Volume (gal) = your tank’s real water volume Product Strength = 0.40 µg/L per mL in 100 gal Examples To raise Rubidium by +3 µg/L in a 300 gal tank Desired increase = 3 µg/L Strength = 0.4 µg/L per 1 mL in 100 gal DOSE = 3 x 300 = 900 = 22.5 mL 0.4 × 100 40 2. To raise Rubidium by +3 µg/L in a 50 gal tank Desired increase = 3 µg/L Strength = 0.4 µg/L per 1 mL in 100 gal DOSE = 3 × 50 = 150 = 3.75 mL 0.4 × 100 40 DOSING METHODS: Recommended Method: Mix the recommended dose into Perfect Corals Complete Tank System to dose with the 2-part solution daily. Each trace element can be added to the corresponding bottle of our Complete Tank System that contains the specific Trace Element for an added boost to your tank supplementation. By Hand: Can be dosed directly into your tank by hand in a high flow area, using the included dropper or with a separate measuring tool over a minimum of a 2-3 day period. 2 Day dosing: Add 2/3 of the total recommended dose on day 1, 1/3 of the recommended dose on day 2 3 Day dosing: Add 1/3 of the total recommended dose each day for 3 days Add into Dosing Container: Can be added to a dosing container. To extend the dosing schedule, the product can be mixed with RO/DI water into a dosing container.
