BG162299435 I received mine too and have the same issue. Luckily I have made Hypochlorous Acid before and have been experimenting with this device: the first button to the left runs the device for 7 minutes The middle button runs device for 13 min the far right button runs device for 49 sec. Use the middle button for 1200ml 13 min Use the 1st button for 500ml Use 2 scoops of salt (non-ionized if possible) for 1500ml and one scoop for 500ml. I don't use the 49sec button I guess that is for very low doses run until there is a faint bleach smell which indicates the presence of hypochlorous acid. For a more powerful solution add 2 teaspoons of %5 vinegar to 1200ml and a teaspoon of vinegar to 500ml. this lowers the PH and frees more of the chlorine. The best solutions are around 6 ph and without the vinegar you will be around 9 ph basically bleach (sodium hypochlorite) Invest in a ph meter for accuracy. Hope this helps and stay safe!
