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.

Replacement stickers are on the way!!
Color: silver, Color: silver
Edit: Customer service was lovely and I have replacement stickers on the way. This fabulous product has helped me so much and I can't be without it. Back up to a 5 star review. I purchased this product in April 2024. The stickers that help the laptop 'grab' onto the stand are either gone or unstable. See picture below. Can it be repaired with new stickers? How do I get them?

Sixty Bucks? Yep. And I'd buy another one.
Color: silver
OK, I had my doubts. Yes, the iLevel2 is highly-reviewed. And yes, it's really (really) important to have your laptop screen at eye level (get it? iLevel?) But spending 60 dollars on an adjustable laptop stand? Couldn't I just pile up a couple of old books for free? Well, as a contractor once told me when I made a really dumb suggestion, "You COULD do it that way..." The iLevel2's main virtue is that the angle/height adjustment knob is rock-solid, as is the platform. It's just an extremely well-made, solid product. And the adjustment knob, which is on a left-right track on the front of the product, allows you to dial in your laptop's screen height to the millimeter. Result: a totally-custom, ergonomically-friendly setup. Love it.

Underwhelming
Color: silver
Too much hype. It just holds the laptop. Buy something cheaper. The slide adjuster isn’t useful to me at all.

Useful but not perfect
Color: silver
Useful, but typing with laptop perched on it is unsteady. I use a separate keyboard.

Why are people trying to type on a laptop stand?
Color: silver
So the overwhelmingly negative reviews you'll notice for this product specifically surround the "bounciness" of this stand when someone is typing on it—however what is confusing to me is how people are purchasing a laptop stand in theory to optimize their ergonomics, yet also stretching their arms out and elevating them to type on said laptop once it's raised. the point of a laptop riser/stand is to elevate the screen so that you can maintain a more natural posture. One would assume you have an external keyboard to use in conjunction with your laptop once you place it on a RISER, because the idea is to elevate your laptop as a SCREEN and then have a level/flat surface to type on, thereby alleviating any awkward hunching or neck strain looking down or anywhere not naturally eye-level. as it is, it's a perfectly functional and elegant laptop riser. I don't find myself wanting to adjust the height often if ever, but in the one or two instances I experimented with it, found no mechanical issues. It looks nice with Apple hardware and allows me to have my laptop's screen flush with the bottom edge of my additional external monitor, so it serves my purposes well. for people complaining about how it bounces when they type on it ... STOP typing on your laptop's keyboard when you have it elevated on a riser! this defeats the purpose and probably also makes your arms tired—buy an external keyboard!
