Eudrakon P phosphate fertiliser

Phosphate additive fertiliser

In contrast to the majority of other aquariums, some heavily planted and illuminated tanks with moderate to low fish populations require a supplement with the basic nutrient phosphorus - P or phosphate - PO.4.

Composition

Contains potassium dihydrogen phosphate (KH2PO4)

Dosage

1 ml added to 50 litres of aquarium water increases the phosphate content by 0.1 mg/l

The target value is in the range of 0.1 - 0.2 mg/l phosphate. More is rarely necessary and usually only promotes algae growth unnecessarily.
(At the same time, the salt used reduces the potassium content by a slight 0.04 mg/l increased)

Phosphate can also be added as a top dressing. To ~ 0.25 mg/l and only top up again when the level has been at zero for a while.
Aquatic plants are good at storing phosphate, and this method can be used to make life difficult for algae, which are not so good at storing phosphate due to their small size.

If the measured PO4-concentration in the aquarium water before using Eudrakon P has not been detectable for a long time, it is often the case that the first 7 - 14 days of use show a greatly increased consumption. This is normal and is due to the fact that, on the one hand, all plants replenish their depleted phosphate stores and, on the other hand, phosphate is fixed by adsorption on iron hydroxide precipitates in the filter and substrate.

Caution

Adsorber materials that are offered for silicic acid binding (SiO₂) always bind phosphate to a greater or lesser extent!
So if you want to permanently increase the phosphate content of your aquarium water, you have no choice but to remove such silicate adsorbers from the water cycle.

DRAK ist meine Wahl seit NewsGroupZeiten...

Hier in den Becken ist Phosphat immer gegen Null. Ich verwende den P als Stoßdünger immer direkt nach dem 14tägigen Wasserwechsel 1ml/50 Liter. Bei dem Eudrakon P - Pulver kommen zum Auflösen 7g auf einen Liter Wasser. Löst sich recht gut auf, ich verwende dazu 80°C heißes Wasser.

Ideal bei PO4 Mangel

Ideal bei PO4 Mangel,was bei mir öfter der Fall ist trotz intensiver Fütterung.

Nie wieder ohne Kremser Dünger

Dank einer Empfehlung habe ich meine Dünger hier gekauft und mit Dosierpumpe mein Aquarium optimiert. So schön war es noch nie :-) Sowohl der fertige Dünger als auch das Pulver zum selber mischen ist zu empfehlen. Vielen Dank für die tollen Produkte!

Auch hier: Empfehlung Pulver, preiswert und ewig Haltbar

Zur Stoßdüngung bei Phosphatmangel. Je nach Fütterung kam es hier mal dazu, gerade im Sommer, wenn Lebendfutter und sehr wenig Frostfutter auf dem Plan steht.

Immer top

Ich verwende den Dünger seit vielen Jahren und habe nur gute Erfahrungen damit gemacht.

Roots conquer the forest

When designing this aquarium, a friend's photo of a large root forming a kind of subway served as inspiration.
