Citazione: Recipe #1 is for use in aquaria where the pH is normal to low. It will have a pH raising effect due to the elevated pH of the alkalinity part, as do most of the commercial two-part additives. The rise that you get will depend on the alkalinity in your aquarium, and, of course, on how much you add. If you add on the order of 0.5 meq/l of alkalinity then the pH will rise about 0.15 to 0.35 pH units immediately upon addition (and higher locally before it has a chance to mix into the whole aquarium). Recipe #2 is for use in aquaria where the pH is on the high side (above 8.3 or so). It will have a very small pH lowering effect when initially added. The drop that you get will depend on the alkalinity in your aquarium, and, of course, on how much you add. If you add on the order of 0.5 meq/l of alkalinity then the pH will drop by about 0.04 pH units immediately upon addition. The pH may later rise if the aquarium is permitted to blow off excess CO2. This recipe is half as concentrated as Recipe #1. Recipe #1 Part 1: The Calcium Part Dissolve 500 grams (about 2 ½ cups) of calcium chloride dihydrate Part 2: The Alkalinity Part Spread baking soda (594 grams or about 2 ¼ cups) on a baking tray and heat in an ordinary oven at 300 °F for 1 hour to drive off water and carbon dioxide. Dissolve the residual solid in enough water to make 1 gallon total. These two solutions are added as frequently as necessary to maintain calcium and alkalinity. In some light to medium demand aquaria, you may not need daily additions, especially for calcium. Nevertheless, unless testing shows that you should do otherwise, add equal amounts of Parts 1 and 2 over the course of a week. Recipe #2 Part 1: The Calcium Part Dissolve 250 grams (about 1 ¼ cups) of calcium chloride dihydrate (Such as Dowflake 77% calcium chloride) in enough water to make 1 gallon of total volume. Part 2: The Alkalinity Part Dissolve 297 grams of baking soda (about 1 1/8 cups) in enough water to make 1 gallon total. lui usa sempre i stessi componenti (calcio cloruro diidrato e sodio bicarbonato) con sempre le stesse proporzioni.... solo che la ricetta 1 è più satura rispetto alla 2.... non capisco come possa variargli il PH frà le due soluzioni... Sbaglio ?

E ti sembra poco ? Raddoppia la quantità di tamponi inseriti e come conseguenze il pH tende ad essere più alto (sarebbe meglio dire che tende a non scendere velocemente)
