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.

Stays strong with hot or cold food!

Love these bowls! No extra curl on the lip which makes it easier to drink the leftover milk after eating all the cereal, lol!

The difference between 16 oz. and 18 oz. is hard to detect.
Size: 18oz brown
These bowls don't appear to be 18 oz. In fact, they look like they're smaller than my "paper" 16 oz. bowls. Perhaps they are deeper. Still, when I put food in them, they hold pretty much what the paper 16 oz. ones do. I chose them, again because I thought I made a mistake previously to this order. I wanted the sugar cane, heavy duty, microwavable bowls that these are advertised to be. Everything is as described except the size. I'll have to make note that I shouldn't buy these because the oz.'s advertised will persuade one to buy them.
