Brighty K



Brighty K

The three basic nutrients (or macro nutrients) required for aquatic plants to thrive are Nitrogen (N), Phosphorus (P) and Potassium (K). Unlike nitrogen and phosphorus, which can be replenished naturally, potassium has no way of naturally occuring in the aquarium. Brighty K provides the necessary potassium for aquatic plants to thrive. Can also be used as a water conditioner to neutralize chlorine.

Product Description

Brighty K, just like the Green Brighty STEP series and Green Brighty SPECIAL series, uses desalinized deep sea water containing rich minerals that aid in leaf coloration when compared to normal purified water.

Nitrogen, Phosphorus and Potassium all must be present simultaneously and in equal values for aquatic plants to thrive. Nitrogen and phosphorus are replenished naturally in the ecosystem from fish waste, the soil substrate and dead leaves of aquatic plants. However, potassium is not naturally supplied into the aquarium, so it must be supplemented via fertilization.

When potassium is in shortage, the rate of photosynthesis in plants is reduced and their leaves turn yellow or white. Additionally aquatic plants then lose their resistance to algae. Potassium makes plants healthy by stimulating the metabolism and growth of roots, aiding in the plant’s ability to photosynthesize. Brighty K’s main ingredient is potassium, and through ion exchange can also neutralize chlorine in the water, which is toxic for the aquarium and often occurs during water changes.


Use Brighty K alongside Green Brighty STEP 1, 2 or 3 (and SPECIAL Lights or Shade if necessary) daily in the aquarium. Supply 1 squirt (1ml) per 5 US gallons (20l) of aquarium water.
