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 sink caddy
Color: Gold, Color: Gold
It was exactly as described- looks nice on my counter. I haven’t bought the scrub brush I want yet to put in the taller space but it def dries fast anytime water gets on it. I like the look on my counter space. It’s not flimsy, I like the color of the gold.

Effective!!
Color: Black, Color: Black
This caddy keeps my sink organized. It absorbs the water when I place my sponges on it and its super easy to keep clean. I squeeze as much waster as I can from the sponges so it doesn't wear out. I've had this a little under a year and it has held up exceptionally well.

Perfect for beside any sink even dorms
Color: Black
I bought this for my son for his dorm room for his sponge for washing dishes and for him to put his dish soap and his hand soap for everything that he could keep it all tidy because he’s actually quite organized and he actually really liked it and it looked very neat. It’s easy to clean. It wasn’t too big everything fit perfectly for the Myers hand soap, and dish soap. The color is neutral almost masculine is gray and black. And there is no issue of it falling because he kept it on a side table away from the sink so that nobody else would use it so it would be just his. So It was altogether and kept everything organized. He really liked it.

Great Holder for the kitchen sink
Color: Black
The Sponge Holder is exactly as pictured. We use it to put our very sharp knives in so they are not in the sink when we go to fill the dishwasher.
