Hi guys.
I'm a big fan of the co-op from Brazil and would like some help.
I'm having problems with my plants growth, and i don't have easy options for fertilization or light.
My plants seem stagnant, they don't die, but they aren't thriving.
I don't have access to a fluval 3.0 or something like that, they are not sold here.
The plant specific lights are really expensive and i can't afford them.
So, this is my ~20g planted tank, picture was taken October 28:
At the time of these pictures the tank was inhabitated, but now I added 5 albino corydoras (pics from today):
I have tried to add more hardness to my water with calcium and magnesium carbonate but that didn't help with plant growth (that's the white dust all over everything).
I use a popular substrate from a brazilian company by recommendation of other fish-keepers that have had success with it, which has these specifications:
Formula:
TiO................................ 0,05%
K.....................................0,24%
Ca................................. 1,05%
Mg............................... ..0,84%
Fe................................. .0,27%
Al................................. ..1,16%
Si.................................. .6,35%
N.................................. ..0,40%
P................................... .0,07%
S.................................. ..0,34%
Na............................ ..0,0009%
PPM:
Mn....................................166,
9Zn....................................292,5
Cu......................................14,2
B........................................63,8
electric conductivity 1.600 (umnhos)CTC...................15,5(me/100g)
humidity.............................10%
My light is a 50w led reflector like this:
These are my tests results from last week (i use SERA tests):
PH= 7.5
GH= 3 drops
KG= 2 drops
nitrate= 10ppm
Temp: ~80º F
I don't have CO2.
I have these fertilizers at hand, but they don't seem to do anything (even dosing 2 times the recommended amount.):
Each dose adds the following:
NPK:
6.0 PPM NO3
1.0 PPM PO4
3.8 PPM K
0.6 PPM Mg
Micro:
0.07 PPM FE
0.01 PPM B
0.06 PPM MG
0.05 PPM MN
0.01 PPM ZN
0.01 PPM CU
Potassium:
2.5 PPM K
Iron:
0.4 PPM FE
Any idea of what i'm doing wrong?
Thanks in advance.
Sorry about all the information.
