  • 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

Not all the same! Some Great, some not.
I bought the queen 2 pillow green blue pillows first. Absolutely love them. Later I saw they had them with cooling on both sides and bought the queen 2 pillow set of that..not the one that said firm. These new ones are way over stuffed and very firm, they do not sink in softly like the first ones. So I would only get the green/blue tag ones they are 5 star-best i have used, this last one 3 star and regretting them. I took enough stuffing out of the two new ones to make 1.5 new pillows, now descent but not the soft comfort as the first, I thought that was what I was paying for. So it's a gamble. The lighter color stuffing is soft and has more of a memory foam reaction, the other darker one feels like stiffer foam with more air in it. It's still soft but doesn't feel like memory foam.

Starts off very cool
I got this pillowcase for my husband because he is always hot at night and has trouble falling asleep because of it. The fabric of this pillowcase feels very similar to a cooling pillowcase that I have had for years and love (but is discontinued, so I can't get any more of them). It is a silky smooth, not-quite-satin fabric that feels initially very cool to the touch. It fits on a standard size pillowcase, and has a slight pocket end (not very much overlap, so it does come untucked during the night). My husband reports that this pillowcase is very cooling right when he goes to bed, but after a short while, it warms up and isn't really cool anymore. So if he doesn't fall asleep right away (and he usually doesn't), he has to flip it over. His head puts out a lot of heat at night though, so the pillowcase might stay cooler longer for others.

Doesn’t stay on the pillow.
Color: Gray, Size: Queen (2 Count)
The concept is there, but the pillow case doesn’t stay on. Every night the pillow case slides either half way or completely off the pillow. If it stayed on I would love it
