[bslong]

other than light and CO2, wat other macro and micro-nutrients is needed???

is the seachem's flourish iron, potassium, excel, trace, nitrogen and phosphorus line of products sufficent???
it seems better than those complete liquid fertilizers, cos i will be able control the specfic amount myself, izzit??

or is there other better products to recommed???

pls advice....thks

Seachem line of products does have the full range of fert but can be a bit expensive to dose for a large tank. For more economical ways of dosing, you can get stuff from Dr Mallick.

Macronutrients: Nitrate, Phosphate, Potassium, Magnesium, Calcium, Carbon
Micros: Too many stuff to name...LOL..just use TMG, Flourish or Sera liquid traces.

Getting CO2 to 20-30ppm range is vital before you start dosing.

will like to increase the GH level in my tank, heard that calcium carbonate will rise the level is that true???

does the calcium carbonate also provide calcium needed for plant growth?

where can i get calcium carbonate and magnesium???

[PeterGwee]

Singapore's water calcium and magnesium levels are adequate for plant growth and should be sufficient if you do large weekly water changes. GH does not affect growth that much as compared to Nitrate, CO2, potassium and phosphate.

so how do u calculate the CO2 PPM? is there a chart for it?

[PeterGwee]

Use pH and KH readings and compare it to this CO2 chart for CO2 reading.
CO2 chart

Do take note that peat or other forms of buffer in the water would render the pH/KH relationship useless.
