Good morning,
A tank running since first June 2016.
Specs:
100 real liter tank
CO2 Injection 20 to 25 PPM
Fertilization by Tropica Specialised 10 to 12 Pushs a day.
Water change 30% twice a week
Highly Planted with Tropica Pots 1/2 grow of 15 different species.
Led Lighting 4000 lumens, very good filtration, maintenance routines etc etc. bla bla bla.. no need to go further on this
No signs of any algae since assembling till today. Tank runing perfectly. All plants looking beautiful except for one.
The person was doing water tests every sunday since June 2016. In all tests along this months the results were always nearly the same.
NO3 between 10 to 15 Ppm
FE Between 0.4 to 0.6
PO4 - 0.1
So.. this guy decides to boost specificaly PO4 in order to see if some improvement came along with that plant that was not on good shape. A bottle of water and some powder of KH2PO4 and a receipe in order to acomplish 1 PPM for each 10 ML dose.
So here we go.. (also continuing dosing the Tropica Specialised 10 Push a day)
Monday.. add 10 ml before photoperiod. PO4 measures after photoperiod point to 0.4 PPM.
Tuesday .. add again 10 ML more before photoperiod. PO4 measures after photoperiod point to 0.4 PPM.
Wednesday.. same 10 ml. Again.. 0.4 PPM
Bought a new JBL test to measure and compare.. just in case. Ok we still got 0.4 PPM. For god sakes.. could it be of the powder? No matter.. bought a new bag of KH2PO4 and here we go again. (Sounds like Whitesnake..)
Thursday add 20 Ml of the solution. (He tought: "I don´t care let´s see what happens i don´t give a damn.. wf is going on??) Again.. for his surprise dosing the double he achieved 0.6 PPM..
"Wow.. "
Fryday.. more 20 ML.. and a final result of 0.6 PPM.
But now he decide to measure the others to.. and guess what ? FE was almost at 1 PPM. (?)
Concernings:
Why and how this PO4 consumption if it never occured before?
If plants till now never eat this much with the Tropica Specialised and looking very very beautiful what is going on in the tank since this guy decides to add more PO4?
What happen in the relation between PO4 and FE so that since PO4 was added iron increase that much?
One thing is for shure.. the plant still looks the same and did not improve a damn thing.
So PO4 is out of the question as the other elements. (I guess..)
But this water/elements/chemistry behaviour and this consumption really drives us for many questions.
Any thoughts?
Best regards
