Seachem Reef Potassium

Seachem Reef Potassium is a potassium supplement designed to support the growth and coloration of corals and macroalgae in reef aquariums.

  • Potassium Supplement for the Reef Aquarium
  • Supports Growth and Coloration
  • Concentrated 100,000 mg/L Potassium

Potassium is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. In systems supported with nitrogen and phosphorus supplementation, potassium utilization rates may be increased. Supplementing with Reef Potassium™ provides a targeted means of increasing potassium concentrations effectively without also adding phosphate or dissolved organics.

In many reef aquariums, potassium supplementation can enhance coral and macroalgae growth and color – particularly red and pink colors in corals.

Reef Potassium™ is ideally suited for use with an aquavitro® sentia™ dose doser to maintain potassium at consistent concentration based on your aquarium's unique demand but is easily dosed manually as well. Ideal potassium levels will vary but generally range from 380 - 400 mg/L potassium. Reef Potassium™ contains 10% elemental potassium. Use Reef Nitrogen™ and Reef Phosphorus™ to maintain optimal nitrogen and phosphorus levels.

Directions:
Beginner
Use 1 cap (5 mL) per 160 L (40 US gallons) twice a week or as needed to maintain desired potassium levels.

Advanced
The beginner dose raises potassium by 3 mg/L. To target a specific potassium level, increase dose according to the following formula: 0.01vn=m where v= volume of tank in liters, n=desired potassium increase, and m= volume of product to use in ml. For example, to raise 160 liters by 3 mg/L potassium you would use 0.01*160*3 resulting in 5 mL to dose. For reference: 1 US gallon=3.8 L.

For the Back Pocket Carrier out there....
Material Type: Leather, Color: Forest Brown-4337
I think this wallet is awesome! I've been carrying for about a week and it is working out great. I usually don't carry cash but for the last week, I've actually had a little cash on me. Instead of using the clip on the back (that clip is pretty tight and I don't like the look of having cash there), I just put is under the ID flap and the magnetic closure holds it in place. I love the color, the trigger works great, and the cards are held securely even when it isn't completely full. I also like the size. It requires me to carry less, which is something I need. (I realized two weeks ago that I had been carrying an old debit card in my old wallet around that had expired in 2023 and it turned out that I didn't have an account at that bank! hahahahahaha. I must be getting old.). This is important to me: I carry a wallet in my back pocket. I always have and that is what is comfortable to me. Front pocket carry feels weird to me. I've been carrying this wallet in my back pocket and sitting on it with no issues. I'm a big guy (300 lbs) and, so far, it's held up great. In all honesty, I do take it out of my pocket and put it in my console when I drive, but that's it. Everywhere else I go, and sit, it stays in my back pocket. I know it's only been a week, but I'm glad to see that I haven't crushed it, or deformed it, or anything. Ultimately, it's been great and I'm glad I got this one.
