I did my first Triton test and they said I was low potassium, everything else was in order. I use the 4 part Triton method via dosser. I started to dos brightwell Chetogro based on element list of product. I figured my cheto was pulling out all my potassium. I been dosing 15 ml once a week in my 120 gallon.
Element list of brightwell cheto grow.
"Potassium - Protein synthesis, water and charge balance, enzyme activation.
Boron - Chlorophyll production, flowering, root growth, cell function.
Carbon - Required for all organic compounds.
Calcium - Cell wall stability and permeability, enzyme activation, cell response to stimuli.
Chlorine - Water and charge balance, photosynthesis.
Iron - Required for photosynthesis, component of enzymes utilized in redox reactions.
Magnesium - Component of chlorophyll, enzyme activation.
Manganese - Formation of amino acids, enzyme activation.
Molybdenum and Cobalt - Required for nitrate reduction.
Nickel - Enzyme activation, processing of nitrogenous material.
Sulfur - Component of proteins and the coenzymes that are involved with nutrient utilization and growth.
Zinc - Chlorophyll production, enzyme activation."
there’s really no obvious reason that organism growth necessarily reduces potassium. When you add foods you should be adding the potassium in those foods, same as they took up when growing.
If you feed potassium deficient foods, k may certainly decline. Dosing inorganic nutrients may also promote the decline.
but the biggest cause of a K drop may be use if a two part that lacks sufficient potassium to offset the salinity rise and correction effects.
