TNC Complete Aquarium Plant Food 250ml / 500ml /1000l

TNC Complete is a ready mixed fertiliser for the planted aquarium, containing a balanced blend of Nitrogen, Phosphorus and Potassium as well as Magnesium and all the important trace elements for a great growth. 

TNC Complete includes 0.0002% Copper, which is 20 times more than in Seachem Flourish, whilst Brightwell's ChaetoGro does not include any Copper.

Copper can be toxic to aquatic animals and invertebrates like shrimp and snails as they are particularly sensitive.
However, copper is needed in trace amounts by both plants and animals.
The amount of copper in TNC Complete is still so small that a overdose would be necessary before it would begin to reach an amount of Copper that is toxic to aquamarine life. 
This said when using this fertiliser we recommend for safety reasons to monitor the Copper level in the aquarium water and to use when necessary Copper removing supplements.     

Instruction Guidelines

  • Shake TNC Complete well before using.
  • Dosing recommendation: 
    Dose 10 ml per 100 litres of tank per week and increase the dosing when necessary up to three times a week.
  • For strong algae growth it is recommended to maintain a minimum Nitrate level of 3-5 ppm and phosphate level of 0.01 ppm, as otherwise an optimum macroalgae growth may not be possible.
  • Concentrated formula & integrated measuring bottle - 500 ml will treat 5000 litres of tank water


Keep out of reach of children. Not for human consumption. Handle with care in the aquarium.
