Uptake Ratio

The uptake ratio is the proportion in which a reef tank uses up elements. The Aqua Care Guide™ calls it the “typical uptake ratio.”

Our Step 4, Bioactive Color Elements™, and Easy Reefer® products are formulated to it. What goes in matches the proportions corals typically take out.

Why It’s Important

• Bio-Gen™ supplies iodide, bromide and fluoride in proportion to the typical uptake ratio. Bio-Kalium™ does the same for potassium and boron, and Bio-Metals™ for its added trace elements.
• Easy Reefer® is based on typical uptake ratios. That’s how two products can cover what Step 3 and Step 4 cover.
• The two Easy Reefer® products are made to be used up at equal rates, which keeps dosing simple.

How It Works

“Typical” matters. The Guide notes that every reef’s natural biodiversity can shift the uptake ratio slightly, so dosing needs can vary from tank to tank.

That’s the trade-off with a simplified routine: less control over each parameter. Easy Reefer® products work alongside the Reef Essential® and Signature Series™ lines when a tank needs fine-tuning.

Uptake Ratio and Related Terms

The uptake ratio describes element consumption as a pattern rather than one element at a time. It covers trace elements like iodine and iron, and others like potassium.

A test can also suggest an element was used when it wasn’t, which the Guide calls false uptake. For more, see Easy or Control: The Debate Between 2-Part and 6-Part Aquarium Dosing.

The Bottom Line

The uptake ratio is the mix of elements a reef typically uses, and products made to it keep supplementation in proportion. Every tank varies a little, so keep testing. See the Easy Reefer® Series.
