Cold War Heroes - How to Use Nutrient Heaters
Pick a Size
You need 1W per Litre of nutrient - e.g. if you have a 150L tank, you need a 150W nutrient heater.
Or, in other words:
|Number of Heaters|
|50 Watt||150 Watt||300 Watt|
|Up to 50 Litres||1|
|Up to 150 Litres||1|
|Up to 300 Litres||1|
If your tank is larger than 300 Litres, just buy multiple heaters.
Whatever size you've got, the instructions are practically the same.
Remove from packaging and clip on the suction cups, if not attached already
Plug into a suitable socket (switched off)
Place it horizontally at the base of your system / tank, and push down gently so the suction cups stick in place.
Twist the dial at the top of the heater to set your temperature - we recommend aiming for around 20oC.
Turn on the mains suppy and leave your heater running at all times
Make sure your nutrient solution never drops below your nutrient heater
