Atoll Potassium
After calcium alkalinity and magnesium, potassium and strontium should be the next two major elements you stabilize. While nsw levels are around 380 ppm, we recommend maintaining potassium levels slightly higher at 420 ppm to provide a buffer and prevent drops in concentration.
Please note that potassium levels in Seachem salt can be extremely high, with ICP tests showing values above 500 ppm. If your liquid reagent test indicates low potassium and you are using Seachem salt, we strongly recommend conducting an ICP test before adding this trace element.
Required Test Type:
Salifert Potassium titration test, Oceamo ICP-OES or ICP-MS
| Parameter | Value |
|---|---|
| Recommended Level | 420 ppm |
| Typical Range | 380–420 ppm |
| Test Method | Salifert Potassium titration, ICP-OES, ICP-MS |
FAQ
What is the recommended potassium level for stable aquarium water?
The recommended potassium level is 420 ppm, which provides a buffer to prevent levels from dropping too low.
Can I rely on liquid reagent tests to measure potassium accurately?
It is not advisable to rely solely on liquid reagent tests when using Seachem salt, as potassium levels can be extremely high. An ICP test is recommended for accurate measurement.
Which test methods are accepted for measuring potassium?
Salifert Potassium titration test, Oceamo ICP-OES, or ICP-MS are accepted methods for measuring potassium levels.

I used this potassium supplement after noticing my tank’s levels were dropping. Following the recommended 420 ppm target, I saw stable readings over several weeks. The ICP test confirmed the levels were within the ideal range. Great product for maintaining balance in a reef system.

The instructions were clear and the product helped maintain consistent potassium levels. I did have to run an ICP test first because my liquid test showed low levels, but that turned out to be due to the salt mix I was using. Now I know to verify with ICP before dosing.

This product is essential for reef tanks. I’ve used it regularly and noticed no fluctuations in water chemistry. The recommended dosage and target level are spot on. My test results match the expected values after a few weeks of use.
