Evo nasao sam bilo mi pod nosom cijelo vrijeme

to je sajt James planted tank ispod kalkulatora nadam se da necu prekrsiti neko pravilo ali kopiracu deo gde je ovo objasnjeno:
Teaspoon quantities
I have calculated the amount of each chemical by weighing the amount using a standard teaspoon (5ml) which is available from most kitchen stores. Depending on where you obtain your chemicals from you may get slightly different weights. I get all mine from Aqua Essentials. Here are the weights I have used for each chemical using one teaspoon:
Potassium Nitrate 6.0g
Potassium Phosphate 6.6g
Potassium Sulphate 5.1g
Magnesium Sulphate heptahydrate 5.1g
Calcium Sulphate dihydrate 4.1g
Calcium Chloride anhydrous 3.5g
(nb.The tablespoon amount is calculated by multiplying the teaspoon amount by 3)
Ovaj mi zadnji dio nije mnogo jasan o cemu on to?
