Potassium Nitrate (KNO3) - 1lb (Jar)


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

The jars were exactly what was looking for

Great for establishing no3 in ULN reef systems

This product worked great... mixed 45 grams of powder with 500ml of ro/di water. I had zero no3 in water and po4 was around .06 I was dosing 15ml. In my 300 gallon frag sustem morning and night until I got around 2-3 no3. It also lowered my po4 to about .04 for a few days, if the kno3 had anything to do with that, Maybe... Product worked great and corals look nice... Plus, I have enough to last 5 years... lol... don’t hesitate buying if you have a ULN system... It will get you where you need to be
