Kodak Fixer using at double strength any dangers?

[10speeduk]

Hi All, I have just started to get back into B&W dev. Today I mixed my Xtol, and Kodak fixer from powder. In the interests of space I decided to make the powder into 1.9 litres instead of 3.8 litres. I used it today for 7 mins with the usual agitation, and it was great. I then poured it back into the bottle. I just wondered if there was anything I should consider taking this approach? Thanks Paul

I take it that the stock solution with Kodak powder doesn't require any further dilution. I can't see a problem except that you are using it at twice the rate.

Not a question you have asked but I'll throw in my two-penny-worth anyway. I'd buy liquid 5L of rapid fixer and decant it into a 5L polypin( like a winebag in a box) and then dilute when ready to use into say 500ml bottle and pour back into the bottle .

Actually fixes more slowly, and acid concentration is too high. Could cause pinholes, drying spots, etc.

Thanks Tom I will buy another bottle and dilute to stock.

you also run the risk of bleaching the film and prints if the fix is too strong ...

The activity of thiosulfate is lesser if you use a concentration too strong. May be you need longer fixing time. Other problems may occur as mentioned.
