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.

Sturdy and well priced
Size: Large 1/2in x 6ft-Rope Clasp, Color: Black
Amazed at the great quality of this leash, very sturdy and reasonably priced. I use it for off leash training, as a leash drag and miraculously it does not pick up any trail debris.

Nice quality leash, good price. Clasp is heavy duty and should handle beach duty. Would buy again in another color.

It is indeed comfortable
Size: Large 1/2in x 6ft-Rope Clasp, Color: Light Blue
I really like this leash. The color is vibrant and I have experienced zero fading even though I leave it outside. I really appreciate the padded handle and the entire leash is a good substantial weight - I hate a flimsy leash. I would not hesitate to purchase this again if needed.
