Ran a test today on the tank:

Ph 7.2
Ammonia (NH3/NH4+) = 0.5 mg/l
Nitrates: NO3- = 0.0 mg/l, NO2- = 0.0 ppm
Phosphate PO4 3- = 0.25mg/l
Kh = 3 degrees
Gh = 6 degrees

First time I ever used test kits on a tank so it it interesting to watch how it goes.

Plants quickly about 50% of tank and a piece of driftwood, no layout yet so no pictures. Just wanted to get something in the tank to go with the soil and help establish it as I was using everything new.

What I am considering now is how I will fertilize this tank. Just over the counter premixed stuff common in Taiwan as with a 110L tank the cost won't be that high. Follow the PPS-Pro method or EI Method.

EI for my tank would be:

KH2P04

20-40 Gallon Aquariums
+/- ¼ tsp KN03 3x a week Potassium Nitrate
+/- 1/16 tsp KH2P04 3x a week Monopotassium Phosphate
+/- 1/16 tsp (5ml) Trace Elements 3x a week Plantex CSM+B
50% weekly water change

(all time 1.5 for my 29 gallon tank as the info is for a 20 gallon tank and you double it for a 40gallon) though if I assume I am running a little lean on the light (I will have less then 3 watts per gallon), then I would start of with the above information and adjust it as growth inproves.

EI target ranges
CO2 range 25-30 ppm - Hardest to maintain with temperature raise
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

PPS-Pro is very simple

Need to dose 1 ml / 10 gallon daily before lights come on so I would need to dose approx 3ml daily

That would mean a 90ml bottle of solution would last me one month!!!
And to make that all I need is:
KN03 = 6g = have it
KH2P04 = 1g = have it
MgSo4 = 4g need to get it
K2SO4 = 5g need to get it
TE = 7grams

according to this Introducing the PPS-Pro Solutions Recipe http://ca.geocities.com/pps@rogers.c...ipe.01.xls.zip

That sounds easy, cheap and not a lot of work, and uses a lot less chemicals then EI.

Great article on the changes in dosing methods and it makes sense to me:
