What is the fixing capacity of TF-4? (do they give a specific number as a guide?)(posted 8490 days ago)I guess the pH of TF-4 must wait until someone measures it. (I'd greatly appreciate if someone could dip in a pH indicator strip. I don't need accuracty to 1/10 of pH...)
If TF-3 smells because of high pH, it seems that the next step is to lower the pH a bit. Perhaps by adding some sodium metabisulfite or sodium bicarbonate (baking soda)... this is something I can easily try...
