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.

Nice looking, heavy duty paper towel holder. Looks like it'll be durable. The top did have a couple of dark, tarnished looking spots but it's not too noticeable.

Free Mini-Screwdriver + microfiber cloth? Thank you
Color: Gold, Material Type: Stainless Steel
100% worth the purchase mainly for the little screwdriver (a real one, just small) and microfiber cloth included. As long as you install it correctly it all holds together very well.
