Short story :
I was sick a couple of weeks ago. So no one taking care of my tank at that time. My downoi suddenly become ill like the photo above. I've tried to raise the dose of KNO3, KH2PO4, K2SO4, but didn't show good result.
My friend said that vitamin B1 can prevent stress on terrestrial plants. So I tried to give it into the tank, and no results.
and the other suplement is booster bacteria that used to raise production for farming. and yeah, no results.
I'm getting hopeless now
Dimension : 60x30x35cm
Substrate : Malang Sand (contains the majority of Mg and Fe, made for bonsai growing media), DIY based fertz, NISSO Soil, Silica sand
CO2 : 2bps
Lighting : 23w x 4 tornado tube
Liquid fertz : DIY Macro nutrient = +/-20ppm; Micro nutrient = +/-10ppm
(i've tried to give dry dose, but can't measure the right portion, so i get back to make my own liquid)
Macro Nutrient (concentration in 1ml, i'm using 10ml) :
My friend's calculator
NO3 - 0.245313364 ppm
PO4 - 0.020936397 ppm
K - 0.271002178 ppm
Mg - 0.009861017 ppm
Web calculator (1ml)
NO3 - 0,99 ppm
PO4 - 0,1 ppm
K - 2,78 ppm
MgSO4 - 0,5 ppm
Water parameter : GH = 2; KH = 0-1
oops, sorry..forgot something..today i give it a DIY root fertz using AMAZONIA II as a mixer (contains KNO3, KH2PO4, K2SO4, MgSO4, and Na2EDTA)..dont know what will happen..
kinda funny btw, when i had a flashback, the question arises "what did i do?"..hahaha
