Aquarium fertilizer (PMDD)

Fertilizer PMDD: prescription and dosage for the aquatic plants

First of all: this prescription is not one my production… but is at this point patrimony of the community acquariofila! : -)
The situated one from which it has been originally taken is this.
The PMDD (poor man dosing drops or fertilizer of the poor ones) is based on the studies of Colin & Sears and regards the realization of a fertilizer for Aquarium that allowed to the aquatic plants of having the windward on the alghe. In fact the game as we know is here all, better they are the plants and less alghe we will see in our tropical sweet water Aquarius.
In average liter of water of osmosis (or distilled, as that one for the iron from I iron) you melt:

1. 1 spoon of chelati elements LACKING IN N-P-K (the found ones in the vivai to L. 10,000 scato it from ten envelopes)
2. 1 spoon of MgSO4, Magnesium sulfate, (the found ones in pharmacy with the name of knows them English to 800 L the envelope) melted in 7 water spoons. It goes ONLY inserted if the GH is advanced to 4-5°- 2 spoons of K2SO4, sulfate of potassio (the found ones on a commission basis in pharmacy)
3. 1 spoon of KNO3, nitrate of Potassio (the found ones on a commission basis in pharmacy). With fish in bathtub it does not have to be put!!! I have paid 30,000 Liras in pharmacy for means chilo of KNO3 and means chilo of K2SO4.

If considered the fact that of every element comes uses you between the 10 approximately and the 20 grams you will notice of like, dosing twenty or so drops to the day, the cost is absolutely ridicule. The doses according to vary the ability to the Aquarius, of the amount of plants, the amount and quality of the lighting system and the CO2. A system in order to quantify the optimal dose is the test of the Iron, than it does not have to never exceed the concentration of 0,1 mg. /l. Remembered but that is also much difficult to measure iron in Aquarius, because is an element that comes ENDURED absorbed, therefore is nearly useless, better to see if evidences of one exist deficiency of iron on the leaves and the colors of the plants.

Personally I have used this fertilizer for some years and with great satisfaction. : -)
Of it I poured approximately a stopper of every bottle 50 liters, 2 times to week, and I added some of the other for the changes of the water.
The dose for your bathtub you must by themselves find it, beginning with one small amount and increasing it single after 1 month of test, for the plants the times for whichever variation in Aquarius are much long.

If you have personal experiences with respect to this fertilizer PMDD, they tells to you low through the comments, all the acquariofili will benefit some! : -)
