  • Potassium supplement for enhanced plant growth
  • Easy-to-use dispenser for quick 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).

While other brands require you to measure out certain milliliters or capfuls, we offer two sizes of Easy Potassium that come with easy-to-use dispensers for quick dosing. For most planted aquariums, get the 500 ml bottle with the pump head that treats 5,000 gallons total. For nano tanks smaller than 10 gallons, the 120 ml bottle with the dropper cap is perfect and treats 1,200 gallons total. 

Directions/Specifications

Recommended Dosing Instructions:
1.  For the 500 ml (16.9 oz) bottle, dose 1 pump (1 ml) per 10 gallons of water, one to three times a week. Each pump adds 2 ppm potassium to 10 gallons of water.

2.  For the 120 ml (4 oz) bottle, dose 2 drops per gallon of water, one to three times a week. Each dose of 2 drops adds 2 ppm potassium to 1 gallon of water.

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 and dropper cap are not leak proof. For optimal shelf life, store out of light.
— 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

Kinda of a cool gadget
Color: Cool White
I really didn't know I needed this until I got it! Easy and quick to recharge batteries (they do not come with rechargeable batteries). Put out enough light for an evening outside around the table

Love the Warm Glow!
Color: Warm White
This light is very easy to install and has 3 different lighting options. I love the warm white light it emits as opposed to a bright white light that could attract bugs at night. Perfect light for patio, deck, camping, golf cart, etc!

It feels cheap and works just okay
This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!
Color: Cool White
This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.

A lovely gentle cleanser - good for rosacea-prone skin
I have also purchased the Thayer's Milky toner and really liked it. I normally use oil-based cleansers, like Beauty of Joseon ginseng oil cleanser (which I still do love), and Cosrx makes a snail mucin cleanser that I use for cleansing off makeup or sunscreen and it's very nice. But for my daily regular wash, particularly in the morning, I like a very gentle easy-to-wash-off cleanser that hydrates and soothes. This Thayer's has no perfumes/fragrances! Good for rosacea-prone skin. Hydrates and soothes very well. It didn't strip my skin, wasn't oily at all (though good oil-based cleansers do feel oily they don't stay oily), and felt wonderful as I cleansed my skin - also washed away very easily and quickly; I do about 14 or so splashes of water to be sure all is removed then use a washable reusable toner pad with toner to remove any lingering residue. It doesn't make my skin feel tight or dry. It is gentle. It doesn't lather up, which I like since I don't use lathering products or soaps on my face. No burning, itching, redness, or any irritation at all. I normally use K-Beauty but Thayer's is one brand I will use that's not in the K-Beauty products category. It really is a lovely cleanser.
