It’s says it’s based on all natural ingredients? So maybe not glutaraldehyde.
Wish we had the formula, Citric Acid is cheap enough.
It's based on the Citric Acid cycle that occurs in a plant when metabolising. It is not said that Citric Acid is actualy in the formula.. But if one that bought and uses it, dipping a Ph meter in it could reveal if its acidic or not.. I have no clue.Wish we had the formula, Citric Acid is cheap enough.
Hi Folks,Are there any organic compounds (i.e. sources of carbon) that aquatic plants can absorb in sufficient quantity to sustain them - other than glutaraldehyde?
Hi Folks,I've just realized that we're not only talking organic compounds. Inorganic compounds/ions could also supply carbon and they do, e.g. bicarbonate (HCO3-).
Hi @X3NiTHI’ll hazard a guess that it’s a brown liquid and if it is then likely to be Humic and Fulvic acids which are pretty good chelating long carbon chain molecules most easily uptaken by plants...
I think you may be quite close, from Dennerle website:Citric acid based
Thank Darrel for this summary article
If you google Citric Acid Cycle in plants you find a lot of articles and videos on it.
I don't know enough about this complex if this cycle can be enhanced by adding citric acid only. All tho it might be, quite a lot of people add acid (Vinegar) to their planted tanks and report enhanced plant growth. Adding acid lowers the pH and frees up carbons and other elements in the water column for plants to use. If plants use the acid also for other means I have no clue about...also known as the Krebs cycle or tricarboxylic acid (TCA) cycle, is a series of chemical reactions in the cell that breaks down food molecules into carbon dioxide, water, and energy. In plants and animals (eukaryotes), these reactions take place in the matrix of the mitochondria of the cell as part of cellular respiration.
My guess would be that the majority of them are using the CO2 until you get well above pH7.In fact, at pH = 6.5, the DIC* mix of CO2 and HCO3- is approx. 50:50. Do plants absorb each of these equally?
Thanks Darrel, i didn't know this thread excisted, it's already 11 years old. Anyway nice read...
Hi @dw1305My guess would be that the majority of them are using the CO2 until you get well above pH7.
