Brightwell Aquatics Potassion - Essential Potassium Supplement

Brightwell Aquatics Potassion is a highly concentrated ionic potassium solution for marine and reef aquaria - an element that's rarely tested for but steadily depleted by skimming, water changes, and uptake by macroalgae and other organisms.

• Concentration: 80,000 ppm potassium (free of phosphate, silicate, and organics)
• Basic dosing: 5 ml per 50 gallons every other day (a 250ml bottle treats up to 2,500 gallons at this rate)
• Advanced dosing: up to 10 ml per 20 gallons daily until reaching target
• Target range: 390-410 ppm potassium (natural seawater is ~399 ppm)
• Available in 250ml, 500ml, 2L, and 20L bottles

Potassium plays a role in cellular function across marine life, and chronic depletion is easy to overlook since it isn't part of most standard reef test kits - Potassion's high concentration means a small bottle goes a long way toward correcting it.

Compatible with: all marine and reef aquaria; test potassium before starting an advanced dosing regimen.
