  • 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

Very strong magnets on both sides.
Size: 12inch
You will want several. I use mine attached to the side of my large metal toolbox to make my frequently used tools easily accessible. But once connected to a large metal surface, it is very difficult to reposition which is a good thing. One surprise though, narrow shafted screws drivers don’t attach very strongly unlike other heavier tools with larger steel mounting areas for attachment. I am purchasing more for other areas in my workshop.

Fantastic
Size: 17inch, Size: 17inch
I absolutely love these for my garage. An absolute must to have to elevate functionality, and space as a whole. Great upgrade. If you get a metal sheet to attach it onto without any screws- perfect. One down side is you can’t put too much weight on it if you are not mounting it by screws obviously. But holds my wrenches like a pro.

The Force is Strong with This One
Size: 12inch
These are pretty robust and strong. Wish they also sold 18” and 25” models, but imagine I would never be able to dismount them. Ordered some more because I ran out of room on the ones I bought.
