Potassion – FAQ

What is Potassion?
Potassion is a highly concentrated liquid potassium supplement designed to increase and maintain potassium levels in marine and reef aquariums.

What does Potassion do?
It raises potassium levels, which supports coral growth, coloration, and overall reef health.

Why is potassium important in a reef aquarium?
Potassium is a major element in seawater and is:

• A component of coral skeletal material (aragonite)
• Involved in biological processes within corals
• Associated with enhanced blue coloration in SPS corals

What potassium level should I maintain?

• Target range: ~390–410 ppm
• Stability is more important than exact numbers

What makes Potassion different from other potassium supplements?

• Ionic formulation for immediate availability
• Highly concentrated
• Free of unnecessary additives
• Designed specifically for reef aquariums

Is Potassion safe for fish, corals, and invertebrates?
Yes. When used as directed, it is safe for all marine aquarium inhabitants.

When should I use Potassion?

• When potassium levels fall below target range
• In SPS-dominant reef systems
• In ultra-low nutrient systems (ULNS), especially with zeolite filtration
• When coral coloration appears dull or faded

How do I dose Potassion?

• Shake well before use
• Typical starting dose: ~5 ml per 50 gallons every other day
• Adjust dosing based on potassium test results

How much will Potassion raise potassium levels?
Approximately 1 ml will increase potassium by ~21 ppm per gallon (estimate; always test and adjust).

How often should I dose Potassion?

• Daily or every-other-day dosing is preferred for stability
• Adjust based on your aquarium’s potassium consumption

Should I test potassium before dosing?
Yes. Potassium should be tested before adjusting dosing to avoid overcorrection.

Can I overdose Potassion?
Yes. Excess potassium can disrupt ionic balance and negatively impact aquarium health. Dose carefully and monitor levels.

Can I use Potassion with other supplements?
Yes. Potassium works alongside other major elements:

• Calcium (Calcion or Reef Code A)
• Alkalinity (Reef Code B)
• Magnesium (Magnesion)

Maintaining balance between all major elements is essential.

What problems does Potassion help solve?

• Faded or dull coral coloration (especially blues/purples)
• Potassium depletion in ULNS systems
• Reduced coral vitality or growth due to imbalance
