  • 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

Nice grinder set
Size: 2.5" x 5.1"
These are a really pretty grinder set. They work well, but after a bit they don't grind as well, and the tops try to come off. They are also NOT dishwasher safe. They will literally melt, even on the top shelf.

Perfect Size & Price
Size: 2.5" x 5.1", Size: 2.5" x 5.1"
Perfect size! Easy to hold and turn the grinder. Grinds both S & P well. Easy to fill and comes with a top to cover grinder when not in use. Perfect look and style for a table or to store for easy reach beside your stove. It also come with 2 extra replacement grinders if needed. An excellent product at a reasonable price! See pic for a size comparison next to a solo cup.

These are great!
Size: 2.5" x 5.1"
I've had these for about a year year and a half and I really like them this morning the salt shaker broke, so I just ordered another set (they're not sold individually) to replace the one that broke. If you should happen to drop them on the floor the plastic top will crack!!

Great addition in my kitchen
Size: 1.7" x 5.1"
I really like these grinders. They are perfect size. I use them for other seasonings that I want to grind up for marinating or cooking. They are adjustable so if I want larger or smaller grinds, easily do-able. Great value for the price. They look nice and are easy to use. Also easy to clean.

Doesn't last
Size: 2.5" x 5.1", Size: 2.5" x 5.1"
This grinder appeared to work great and is one of the few ceramic options available. Unfortunately, the ceramic grinder has already broken inside, detaching from the bottle altogether. There are probably tiny plastic pieces in my leftover peppercorns. Don't buy it unless you want to purchase it every few months, which is unfortunate.
