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 chew toys
Size: Medium, Style: Dog Chew Toys, Size: Medium, Style: Dog Chew Toys
Im giving this 5 stars because the size is perfect for my French bulldog and my mix breed. They like the shape and they are very durable. Usually they chew up anything plastic like big Legos and other types of similar toys. So I figured for the price and quantity this was an excellent deal. At first they could have cared less but since they know they can chew them they do so every so often. Im mind wired when it comes to dog food or treats I smell them and taste them first. And these chews toys were no different. I did not smell any type of bacon sent but maybe he dogs do. They are not obsessed with them but no means but they serve as a chew option non the less. I will put them in a bag of treats to absorb the smell so they are more appealing in that manner. They have yet to make a dent chewing wise unlike the Legos. So they will last. So 5 stars for price..shape..quantity and durability.

Dog toy

It’s a great product and sadly to say it never lasts very long in my house. I’ve purchased others like this, but my pits just teared apart.
