Aquarium Fertilizer - Something to try out.

For fertilizer heat 3 cups of water to boiling in a large jar or measuring cup. Add the following and stir until dissolved:

1. 1/4 cup of potassium sulphate
2. 1/4 cup of epsom salt (magnesium sulphate)
3. 1/8 cup of potassium nitrate (salt peter)

Put this into a 750ml bottle and keep in a cool place. Sometimes crystals may form if its in the fridge so I add a half tsp of muriatic acid and store it on my shelf.

• Add 1 tsp of this for each 5 gallons of aquarium water on startup.
• Each time you change water, add 1 tsp of this for each 5 gallons of water you replace.
• On startup, add 2 tsps of calcium carbonate for each 10 gallons of aquarium water. SKIP this if your tap water is over 4 GH general hardness.
• Each time your change water, add 1 tsp of calcium carbonate for each 10 gallons of aquarium water you replace. SKIP this if your tap water is over 4 GH general hardness. See notes on GH.
• Note that the fertilizer contains no trace nutrient additions. These are provided primarily by your soil.

HINT: mix the calcium carbonate with a jar of water and add this at night around lights off time. It will stay cloudy for several hours. A light layer will also be deposited on the plant leaves but this dissolves slowly by the action of dissolved CO₂ in your water.
