Current stock: 0

Provides nitrogen (N) and potassium (K) to aquarium plants.

Macronutrients essential for healthy plant growth and survival.

N = Nitrogen = chlorophyll, photosynthesis, proteins, enzymes, nucleic acids, amino acids, potassium absorption, metabolism, rapid growth & leaf quality

Deficiency Symptoms -Interveinal chlorosis of older leaves, crippled new leaves, slow/stopped plant growth

Nitrogen is found in chlorophyll, nucleic acids and amino acids; component of protein and enzymes.Potassium Nitrate is a macronutrient essential for healthy plant growth and survival. Provides nitrogen (N) and potassium (K) to plants. Nitrogen (N) is essential for chlorophyll production. Potassium (K) aids protein synthesis and for plants to metabolize Iron (Fe).

Nitrogen is an essential part of chlorophyll, the green pigment of the plant that is responsible for photosynthesis. Nitrogen is a part of all living cells and is a necessary part of all proteins, enzymes and metabolic processes involved in the synthesis and transfer of energy. It helps plants with rapid growth and improved leaf quality. Nitrogen is a major constituent of several of the most important plant substances. For example, nitrogen compounds comprise 40% to 50% of the dry matter of protoplasm, and it is a constituent of amino acids, the building blocks of proteins.

Nitrogen deficiency creates an imbalance of symptoms in plants. Nitrogen deficiency most often results in stunted growth, slow growth, and chlorosis (general yellowing of the plant starting in the older parts of the plant). Nitrate deficiency occurs in plants by yellowing of the leaves, older leaves become yellow and die off, new leaves are small and crippled, growth rate can also be very slow/stopped. Potassium deficiency is manifested by holes on older leaves.

In case of a Nitrogen deficiency, you can increase the levels of available Potassium Nitrate (KNO3). Aquatic plants gain nitrogen from nitrates (NO3). Source of nitrates (NO3) is Potassium Nitrate (KNO3).

Nitrate levels should never be below 10ppm. Optimal Levels: 10 – 40ppm

Working wonders for my Reef!

I dont have a planted tank but I do keep reef tanks and word is out that GLA carries the best pure Nitrate for reef tanks around. I gave this stuff a try and the results have been amazing. I mix 1 teaspoon to 100ml RO/DI. I dose 5ml in my tank raising my nitrates to about 3.5ppm. If your looking to raise Nitrates in your reef tank this is absolutely the stuff to use. Thanks GLA for providing excellent salts for my reef. I also use Kh2po4 in my reef and the results are equally as rewarding.
