Chimica ed integratori marinoPer parlare dei valori dell’acqua e del modo per mantenerli sotto controllo, dei test per le analisi, dei sali marini, dei carboni attivi, dei condizionatori dell'acqua e degli integratori (calcio, stronzio, magnesio, iodio, ecc.).
sì oceanoo ho fonti sia da parte di redsea, sul ciclo del ferro, sia da parte di un chimico su reef central direttamente sul rame...
qui ti posto quanto detto da Ram Sharon sul ferro, che ipotizzo abbia un comportamente simile al ramel: As you probably know sea water contains many chemicals forms, from free ions through inorganic and organic molecules and up to large colloids connected to metals, this “soup” of chemicals increase the probability of spontaneous reactions causing elements to spontaneously switch between phases.
This phenomena is very typical to iron which is switched between seven forms from soluble free ions (Fe⁺³ , Fe⁺²) through inorganic molecules of Hematite and Ferrihydrate to Organic Iron humate and other colloids ( referred to “chelated” iron ) and up to precipitated iron in aragonite lattice.
The important issue we need to understand is that the iron changes its form all the time based on salinity, pH and most by alkalinity and the amount of organics and colloids in the water.
In a closed system like our aquariums, where there is high organic load and many dissolved organic colloids, the amount of free iron could be very small although the total iron could be very high. Usually this situation will lead to a darkening of the corals due to growth in zooxanthellae population and the outbreak of phytoplankton and other macroalgae, and still you may measure nill levels of iron. From the other hand , on very pure salt water, most iron will be as free iron ions which could be very toxic to the tank inhabitants. This is why when you are adding t colors C to 1 liter you can detect high iron level while few minutes later when you add the iron to the tank you measure levels around 0.05 ppm for several hours and the 0after 24 hrs. the iron may precipitated or is bond to organics.

il ferro ed il rame si somigliano come io con mia moglie e non vedo cosa centri con lo spur...
