All the best for your plants in 1 kit

Do you have a planted aquarium? Then you also know how important fertilizers are for your aquarium plants. Without these substances they do not grow or grow poorly and poor plant growth often leads to algae. And you don’t want that, do you?

For healthy plants you need to add fertilizers. But you don’t know exactly what you need and how much to dose? Well, that problem is now solved. In this Estimative Index kit you have everything to spoil your plants: nitrate, phosphate, trace elements, magnesium, …

This way you can be sure that they will grow nice, full and strong.

Would you rather have something ready-made? Without having to mix it yourself? Try the All-in-One Aquarium Fertilizer.

Convenient dosing without weighing

Each bag of fertilizers has an easy quick-start guide that clearly explains how to make a solution and how much to add to your tank for great results. Just mix and dose.

With competitors you need to buy an extra scale to make your solutions, which makes your order a lot more expensive. Not with my kit. With every order you get a free dosing spoon. Just add x number of spoons to your bottle and you’re done. Then just add it to your tank according to the manual and wait for the first results.

Your plants will love it 🙂

How should I make the fertilizers?

That is very easy. With your order you will receive a clear manual that explains how to make the fertilizers. The manual for each product is also stated on the packaging itself.

Do I need precision scales?

No that is not necessary. You will receive a free dosing spoon with your order. You then add x number of spoons, mix and ready. This is a little less precise, but it doesn’t matter for your plants. Moreover, you save a lot of money because you no longer have to buy a scale.

Do I need to buy other fertilizers?

No that is not necessary. This kit contains all the most important nutrients for your plants.

Can these fertilizers cause algae?

No, this package does not contain any substance that can cause algae in your aquarium. Rather, it is a nutritional deficiency in your plants that causes algae. Your aquarium plants stop growing, start to turn slimy and that in turn causes algae. Better to add fertilizers!

How much should I add?

30ml per week of each stock solution on 100 liters of aquarium water. This is also clearly explained in the supplied manual.

Can I make an All-in-One with this?

No that is impossible. All-in-One is stabilized in several ways to avoid precipitation. That is not possible with this kit. It is therefore best to keep phosphate separate from the iron and the trace elements.

I need help, can you help me?

Sure, check out the blog for my advice articles, download one of my free e-books or checkout the guides.

Are these nutrients dangerous for my fish and shrimp?

No absolutely not. This kit contains no hazardous substances. In addition, all fertilizers in this package are certified by the EU and the Belgian FASFC, the organization responsible for safety & quality of fertilizers in the European Union.

Estimative Index Kit

Hans Barten
Prima plantenvoeding

Gebruik de EIK nu een week of 5. Gebruikte eerst profito automatische dagelijkse dosering maar dat werd nogal omslachtig met de EIK. Voeg nu 1 x in de week de 3 delen vd EIK toe n dat werkt perfect. Planten groeien veel mooier n harder met de EIK. Ijzer gehalte blijft zeer stabiel waardoor de rode planten mooi rood blijven. Geen witte randjes/blaadjes meer aan de planten door suiker lekkage. Wat betreft de kosten is de EIK al helemaal perfect........ongeveer een 10e deel ten opzichte vd kant n klaar producten.
Moet wel een week of 3 geduld hebben voordat de resultaten goed zichtbaar worden.
Prima product, makkelijk klaar maken n perfecte ondersteuning vanuit Planter Box.

Zeer tevreden met estimative index

Snelle leveringen en mooi verpakt van de producten. Dit alles met een eenvoudige gebruiksaanwijzing zodat het opstarten geen enkel probleem is.
Het verschil met de planten voedingsstoffen is na 14 dagen al duidelijk te zien, dus ik ben een tevreden man. Grtj

Waardevol aquariumplanten toevoeging

Eindelijk plantenvoeding die meer dan uitstekend werkt. Zeer weelderige groei en de algengroei in balans houd

Estimative index kit

Planten groeien naar wens. Goede omschrijving. Zeer tevreden. Nu de bekende driehoek in balans zien te krijgen en te houden lijkt te lukken. Geen alg.
Tot de volgende kit. Mvg, Reier.
