  • 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

Fantastic foam!
Color: Black, Color: Black
Bought this so I can cut down on my trips to Starbucks and recreate those drinks "to go" at home. It works for making any kind of foam...most recently been whipping up 1/8c half n half with it and added syrups for my iced coffees I take to work. Soooooo worth the money. Starbucks quality foam (if you're not a coffee snob) at home. I now enjoy having iced coffees with salted caramel or chocolate creme cold foam that costs less than $2 to make at home versus $15 at the drive-thru. Time & money saved!

High speed
Color: Sliver
Nice high speed, froths a lovely froth. I like that I won’t be changing batteries every month.

Favorite kitchen gadget!
Color: Black
I bought this for mixing powdered mixes into water, and boy do I love it. I honestly use it way more than anticipated and it works so well. I use it for everything from whisking formula to the intended purpose of frothing milk. Blends quickly and clean is easy, just put a couple of drops soap into water and turn on them rinse! Best money I've spent recently on something for the kitchen, don't even hesitate, just buy it!

Spiral portion of blender did not hold up
Color: Black
It was wonderful for 10 weeks. We used it almost daily and sometimes twice a day. It frothed quickly. It proved a satisfying blender until approx 10 weeks of use. The wire spiral on the end started to slowly wind off. It worked OK but wobbled and frothed weakly at that point. For short term use, for very infrequent use, it will be fine. Looks acceptable, easy to use. Changed the batteries one time. For the price, I am not unhappy. Have now replaced it with a more expensive one on Amazon. Thank you Amazon for giving your shoppers the opportunity to leave our feedback. It is one of your most appreciated features.
