Why do you need NPK liquid fertilizer

For a 20-gallon NPK liquid fertilizer, higher light tank dosing would be as follows:

  • 2 pumps of the micros per day Monday, Wednesday, and Friday
  • 2 pumps of the macros per day Tuesday, Thursday, and Saturday
  • 50% weekly water change is suggested on the 7th day per EI guidelines followed by the addition of the GH booster of your choice

Who needs GH booster: 

The addition of GH booster to NPK aquarium fertilizer is necessary if you do not have very hard water. Adding some GH booster is also suggested if you have hard water but do not know the concentration of both calcium and magnesium.

Why is GH booster suggested when using liquid NPK: 

GH booster will add magnesium and calcium as well as add extra potassium, which is all very important to plant growth.

Do I need to add extra iron to liquid NPK fertilizer products?

For most tanks, the iron that is already included in the Liquid M will be enough.  Some high light, high co2 tanks however will require more iron.  If that is the case, Liquid Iron is a great choice.

 

Dosing Instructions

Full EI levels: 1 pump of each bottle per 10 gallons 3x per week. For lower light/lower tech tanks: 1 pump per 20 gallons 3x per week

 

Liquid NPK

Liquid NPK is tailored to the EI dosing method and it includes micro and macronutrients for plants. This NPK aquarium fertilizer can be adapted to other dosing techniques as well. Bottles are 500ml each and will last more than 41 weeks on a 20-gallon tank dosing 3x per week.

Amazing product
I have just purchased my 7th jar! I absolutely love this product...and its American made! It leaves my skin soft, radiant and glowing! I didn't tell anyone about using it and people started asking me what I was doing differently. I get complements about my youthful glow! This company makes an amazing product and I hope that it will always be available! I have friends and family members hooked on it now. My mom just dropped a stocking stuffer hint to me tonight for another jar!

Legit balm. Not whipped. Made in USA.
Legit tallow balm. Not whipped. I love this stuff. It's the only thing that soothes, softens, and relieves my dry skin in the winter. Also made in USA, which is a priority for me.

Great winter moisturizer! Not greasy & absorbs well!
I needed a moisturizer that would last in colder weather. My skin is oily/normal and works well with my other facial products. I strictly use The Ordinary products and add this at the end to seal in the moisture. Pretty surprised how quickly this absorbed in to my skin. Has no scent and melts quickly on finger tips. I use it on my face and heels of my feet. Honestly love this addition to my fall/winter skincare routine. A little goes a long way! I have been using for a month now with great results. Definitely a great buy!

Great product if you can actually use it
Of the 4 orders I've placed for this lotion, only 2 have come perfectly. One of them came leaking tallow out of the container and package, and then it's replacement arrived with the jar completely shattered. The tallow itself is so hydrating and smells great, but if the company itself needs to fix it's packaging.

May need to transfer to a different jar since the lids break
I am very happy with the product but a little bothered by the packaging. The lid is cracked and doesn't stay on. The fragrance isn't what I expected, but it is pleasant and a comforting smell.
