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.

Squeakers not squeaking
Cute but the problem is the bag was vacuum sealed and none of the squeakers work, even after letting them sit a few days out of package 😥

Disappointed
My multipoo loves his duckie, wrestles with it, sleeps with it, but today he found a weak spot on the back and ripped it, pulled some stuffing out. Have had it about 1 1/2 months. Disappointed! Stu he’d it up but not sure how long it will last🤨

Buyer beware this toy falls apart
I’m sorry to write this review, but I DO NOT recommend this item at all. It is as pictured. It is really cute. It is soft. My dog loves it. HOWEVER, the seams just fall apart. I have bought 3 of these since Christmas and it’s only the beginning of June so five months later and all three of them have fallen apart. Literally the wing will fall off, a foot will fall off and the seams keep coming undone. The stuffing is all over the house. This is one of the cutest stuffy’s. I’ve ever bought for my dog, but it is also the lowest quality and a complete waste of money. Highly recommend that you buy something else.

Durability sucks dont buy
I purchased the Mellow Duck dog toy specifically for its supposedly durable construction, hoping it would provide at least a few weeks of entertainment. Unfortunately, the toy was completely shredded and destroyed within 24 hours of its arrival. For a product marketed as suitable for dogs, the material quality is extremely poor and clearly not designed to withstand even moderate chewing or play. This was a significant disappointment and a total waste of money. I cannot recommend this toy for any dog, as it offers zero long-term value.
