Apa itu EI (Estimate index) method -???
Overview
The Estimative Index (EI) coined by Tom Barr is a straightforward method for providing nutrients for a planted tank. The idea behind EI is simply introducing an excess amount of nutrients within an aquarium, throughout the week. This excess of nutrients floods the water column and feeds the plants. This is an estimative method; measuring specific nutrient uptake rates is not necessary and no test kits are involved. EI provides a surplus of nutrients that helps to prevents plant deficiencies, and allows plant growth to out compete algae growth.
The process of which this is done is simple. Each day fertilizers are dosed, and the nutrients are absorbed by the plants. With this method being estimative, we can dose fertilizers according to general guidelines suited for our particular setup (see below). At the end of the week, one performs a 50% water change to ‘reset’ the nutrient load in the entire system. And then the entire dosing schedule is repeated.
The primary fertilizers are the macro nutrients - Nitrogen (N), Phosphorous (P), Potassium (K), and the micro nutrients – trace elements (Plantex CSM+B, Flourish). Iron (Fe) can also be supplemented if necessary.
The Estimative Index method works best for a high light and well planted aquarium. However it is not limited to lower light setups, smaller quantities of fertilizers should be dosed in those instances.
General Dosing Guideline for High Light and Well Planted Aquariums
(wolfenxxx)
10- 20 Gallon Aquariums
+/- 1/8 tsp KN03 (N) 3x a week
+/- 1/32 tsp KH2P04 (P) 3x a week
+/- 1/32 tsp (2ml) Trace Elements 3x a week
50% weekly water change
20-40 Gallon Aquariums
+/- ¼ tsp KN03 3x a week
+/- 1/16 tsp KH2P04 3x a week
+/- 1/16 tsp (5ml) Trace Elements 3x a week
50% weekly water change
40-60 Gallon Aquariums
+/- 1/2 tsp KN03 3x a week
+/- 1/8 tsp KH2P04 3x a week
+/- 1/8 (10ml) Trace Elements 3x a week
50% weekly water change
60 – 80 Gallon Aquariums
+/- 3/4 tsp KN03 3x a week
+/- ¼ tsp KH2P04 3x a week
+/- ¼ tsp (20ml) Trace Elements 3x a week
50% weekly water change
100 - 125 Gallon Aquarium
+/- 1 1/2 tsp KN03 3x a week
+/- ½ tsp KH2P04 3x a week
+/- ½ tsp (30ml) Trace Elements 3x a week
50% weekly water change
Example Dosing Regime for 29 Gallon:
Note: K2SO4 is not required for dosing unless you need the extra Potassium (K). This K is found in KN03 and KH2P04. Dosing these two according to above will yield sufficient K levels. Therefore, one will be fine dosing only KN03 and KH2P04, and Plantex. If one needs to increase their K levels with K2S04, add the same measured amount as KH2P04. For example, if one is dosing 1/2 tsp of KH2P04, then dose 1/2 tsp of K2S04. In true regards to EI, added excess K is not detrimental in any event.
EI target ranges
CO2 range 25-30 ppm
NO3 range 5-30 ppm
K+ range 10-30 ppm
PO4 range 1.0-2.0 ppm
Fe 0.2-0.5ppm or higher
GH range 3-5 degrees ~ 50ppm or higher
KH range 3-5

pupuk dasar pada awal setup??
Saya selalu menganjurakan pemakain pupuk dasar aquascape yang mempunyai tanaman berakar selain karena Tanaman berakar umumnya lebih suka mengambil nutrisi dari akar , tanaman dengan daun emersed(Darat) teradaptasi mengabil nutrisi 100% melalui akar
Sangat penting pada masa awal setup
1.Tanaman akar biasanya ambil nutrisi dari akar jadi butuh extra adaptasi
2. nutrisi di substrate exclusive buat tanaman<< mencegah algea tumbuh, memang bener nutrisi tidak menyebabkan ALGAE, tapi bukan berarti nutrisi di air TIDAK di pakai oleh algae
kenapa pupuk cair penting???
Dengan assumsi pupuk dasar dan pupuk cair di berikan dari masa "awal" setup maka lambat laun pupuk dasar akan berkurang dan habis, dan kandungan2 nutrisi tertentu mungkin akan habis lebih awal, nah ketika tanaman sudah kurang nutrisi dari substrate maka perlahan2 akan adaptasi untuk mengambil nutrisi dari air .Ketika nutrisi di akar sudah habis total tanaman biasanya sudah teradapasi sempurna mengambil nutrisi di air.
