  • Potassium supplement for enhanced plant growth
  • Easy-to-use measuring cap for accurate dosing
  • Safe for fish, shrimp, and snails

Potassium is a very important macronutrient for planted aquariums. If aquatic plants don't get enough of this nutrient, they can develop distinctive pinholes that are sometimes rimmed with brown or yellow. While Easy Green all-in-one fertilizer already contains plenty of potassium for most planted tanks, Easy Potassium is a useful supplemental fertilizer for people who are running high light planted tanks with CO2 injection or have lots of potassium-hungry plants (like java fern and anubias). 

Please note that we have changed over to dosing caps. Pump heads are still available for purchase. 

1. For the 500 ml (16.9 oz) bottle:
— Use the measuring cap to dose(1 ml) per 10 gallons of water, 1-3 times a week
— Each 1ml adds 2 ppm potassium to 10 gallons of water
— Treats 5,000 gallons total

2. For the 120 ml (4 oz) bottle:
— Dose 2 drops per gallon of water, 1-3 times a week
— Each dose of 2 drops adds 2 ppm potassium to 1 gallon of water.
— Treats 1,200 gallons total
— Great for nano tanks under 10 gallons

When in doubt, start low and increase the dosage after 2 weeks. 

Guaranteed Analysis: Soluble Potash (K2O) 9.12%
— Derived from potassium sulfate and potassium citrate
— NPK rating 0 - 0 - 9.12

Notes:
— Please store the fertilizer upright in a cool, dry location away from children. The pump head (if using an older version) and dropper cap are not leak proof. For optimal shelf life, store out of light.
— If you have the pump head version, keep the tip of the pump clean of debris. Wiping the pump tip after each use helps prevent a mineral crust from developing. If the pump gets blocked up, it can cause the fertilizer to spray in a random direction, so run the pump head under warm water until the blockage melts away.
— Warning: Fertilizer can be irritating if it gets into your eyes, nose, or mouth, and it can cause stomach upset if swallowed. If you get Easy Potassium on your skin, rinse it off. If you get it in your eyes or mouth, rinse thoroughly for 15 minutes. For USA customers,  reference the poison.org website. For Canadian customers, reference dpic.org

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

Full, Fluffy & Perfectly Supportive Euro Pillows!
Item Package Quantity: 2, Size: European, Item Package Quantity: 2, Size: European
These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!

These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows. I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.
