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.

Great product
Flavor Name: Peanut Butter, Size: Medium
I have a very active, medium sized dog (heeler). I wish this product was just a little bigger but it is still a great product. I fill it with pureed meat baby food and freeze. A 2.5oz jar will fill this product about 2 times. This keeps my dog busy for a while. Its also great when she's outside on a hot day. I absolutely recommend this product and at such a great price ($6 when I purchased it) i may buy a few more so I'll always have a frozen one ready when needed.

Extra durable and hard
Flavor Name: Marshmallow & Peanut Butter, Size: Large
Much harder and tougher than most of the chews and bones I get. Too tough for my own dog, but it’s become a favorite of two other dogs in my life who are stronger chewers. Also looks adorable when they carry it around.
