Wat is this product?

Do you have many plants in your aquarium that absorb most of their nutrition through their roots? Then you should definitely give these capsules a try. Unlike clay balls, Crypto contains nitrate, phosphate, iron and all other important trace elements.

Your plants will form stronger roots and grow better as a result.

You want your plants to continue to grow abundantly, don't you?

The annoying thing about many soil fertilizers? They are very volatile and lose their effect quickly. And your plants end up falling victim to that.

Crypto, on the other hand, is made of tiny balls that are coated with a special coating and then stored inside a capsule. This coating gradually releases the nutrients to the soil. The advantage? Crypto lasts an exceptionally long time, up to 6 to 8 months!

Ideal, because your Cryptocorynes, Echinodoruses & other rooting plants get plenty of time to grow.

Contains 12 micro and macro nutrients

Traditional clay balls are mainly rich in iron and possibly other metals, but otherwise contain no other important nutrients. Not really useful for your plants.

Crypto, on the other hand, contains all the nutrients your plants need: nitrate, phosphate, iron, potassium, manganese, … As a result, your plants will form stronger roots and consequently grow better, make bigger leaves and show more color.

No more dust clouds in your tank ...

Do you still use clay balls? That cloud of dust when you stick the clay balls in the soil is super annoying, right? Well, that’s a thing of the past with Crypto.

Because the granules are contained in a gelatin capsule, no dust is released at all and you have time to get the capsules to the roots of the plants without any problems. Moreover, the capsule does not crumble as soon as you push it into the water, in fact, it takes a few hours for it to completely dissolve in the soil.

So you don’t have to rush to plant the plant food capsules!

How should I add Crypto?

Just push directly into the soil, best near rooting plants.

How much should I add?

It depends on the amount of plants. I recommend adding a capsule to the soil every 10cm. Push the capsule a few cm into the soil.

How long do the capsules release fertilizer?

About 6 to 8 months, depending on the quantity of plants. It is best to replace them in time so that the plants do not become deficient.

Is this stuff better than clay balls?

Yes 😉 And I’m not telling you that as a sales pitch, but simply because this stuff contains much more nutrients than clay balls. A clay ball is usually only iron, while this product also contains nitrate, phosphate, etc … contains. Moreover, it does not create a dust cloud when adding it to your soil.

Does this stuff cause algae?

No, in the recommended amount, this product does no harm.

How quickly does the capsule dissolve?

The capsule melts about after a minute or two. So time enough to get the capsule in place in your tank!

Does this stuff give off dust when planting?

No, nothing of substance. So planting is easy & without gunk!

There are little granules floating?

It’s possible. When Crypto has worn off, the granules remain because it only acts as a kind of membrane. Just scoop it away and it’s gone.

How should I store my Crypto?

Just store it in the provided pouch and in a dry place.

What nutrients does 1 capsule of Crypto contain?

Nitrate, phosphate, trace elements, iron, magnesium, … In short: everything your plants need! For a complete overview of the nutrients with their content percentages, please have a look at the guaranteed analysis on the pouch.

Prima spul

Prima spul. Gebruik het al jaren.

Chris Geerinckx

Is de 2e maal dat ik dit bestel. Planten doen het er heel goed mee. Topproduct. Het beste is dan ook dat er niets van stof achterblijft als je eens iets wilt herplanten of de wortels wat bijknippen.

Nico Koppel

eenvoudig en efficient, prima toepassing

Etienne Stouten

Gebruik all-in-one al jaren.
Makkelijk in gebruik.
Al jaren een heldere tropische aquarium met gezonde vissen en goed groeiende planten. Algen hebben hier geen plaats in.

Prima spul

Ik ben prima tevreden met de Crypto capsules, de aquarium planten hebben wel even nodig 1 / 2 weken voordat je langzaam resultaat ziet (1.20m Apisto Cacatoide bak) en 1m Apisto Beanschi Inca bak beiden met veel planten, kienhout) maar je plantjes worden er mooi stevig van zeker als je "abctjes" zoals co2, waterwissels, onderhoud ed.. goed bijhoud. Ook als extra bijvoeding kan ik dit product echt aanraden zeker als je zoals ik 2 goed beplante aquariums heb. Kleuren van de planten lijken ook iets "dieper" en de groei lijkt ook iets beter te zijn zeker bij planten die al even staan en die meer voedingstoffen nodig hebben. Maar de grootste plus is dat het geen afval achter laat (de capsules lossen echt helemaal op) en de waterwaardes worden niet aangetast. Dus ja zeker een aanrader.
