hi there
so i ordered my dry ferts and they arrived. i have a 500 litre tank. i am a bit confused, some articles have recipes including MgSO4 and others only add KNO3 and KH2PO4. others even include KCl. please help, how do i mix the macro solution for my tank.
Using this article these are my calcs when using a 2l dosing bottle and the rotalabutterfly calculator.
If dosed daily:
Nitrate (NO3) 20ppm per week. 20/7 = 3ppm
Potassium (K) 30ppm per week. 30/7=4ppm
Phosphate (PO4) 3ppm per week 3/7= 0.5ppm
Magnesium (Mg) 10ppm per week 10/3=1.5ppm
260.88 grams of KNO3 to your 2000mL dosing container. Add 20mL of that mix to your 500L aquarium daily = 3.2ppm NO3; 2.02ppm K
42.99 grams of KH2PO4 to your 2000mL dosing container. Add 20mL of that mix to your 500L aquarium daily = 0.6ppm PO4; 0.25ppm K
164.93 grams KCl to your 2000mL dosing container. Add 20mL of that mix to your 500L aquarium daily
= 1.73ppm K
1,014.09 grams of MgSO4.7H2O to your 2000mL dosing container. Add 20mL of that mix to your 500L aquarium daily = 2ppm Mg

Mixing dry aquarium fertilisers
What are dry fertilisers? Dry aquarium fertilizers refers to fertilizers that come as pure chemical salts. These salts dissolve in water to provide the necessary nutrients to plants. They are extremely concentrated as they come in pure chemical salt format. Most commercial fertilizers are made...
