    for paper its a bit different as fixer is more dilute.
    I'm using the same rapid fixer @ 1:4 (as Ilfords data sheet) for both film and paper. I use the same working mix and keep track of the usage. At 50% of what Ilford say it will do I am dumping it and starting again. Comments??

    hypo ckeck is a quick and dirty method, but this iodide-based test is too unreliable for archival processing.the indicator tabs are more expensive and more reliable. the clip test is quick and dirty and can be trusted for film.

    Hypo check solutions are not very accurate. Therefore

    1. Keep track of the number of rolls or prints that have been fixed. Do not exceed the manufacturer's rated capacity.
    2. Use the fixer within the manufacturer's estimated life for the solution.

    Always. Fresh second fixer every time, Hypam at film strength, 1liter, which becomes first fixer next session. If I print a lot I mix 2 liters fresh.
    One minute in each, and then on to washing.

    I also always use 2-bath fixing.

    A drop of fixer test in the first bath will tell you when it is time to rotate the baths - you chuck the 1st, rotate the 2nd bath into the 1st position and make up a new 2nd bath.

    The fixer test solution is just P. Iodide. I put a drop in the fixer tray, if a little yellow-white puff appears and then dissipates I rotate the solutions. A ha'penny's worth of P. Iodide from the chemists is all you need: 5g in 25ml of distilled water is enough for 500+ tests.

    It's best to use two solutions for film
    And paper and keep them separate. Film should be 1:4, paper 1:9. I think paper is like 40 8x10 sheets a liter or something along those lines. If you are dumping at half capacity you may be wasting a bit. Film should be like 24 rolls per liter or so. The indicated amounts I think are on the safe side so it's best to check however you like before you use the fixer. You should look into hypam if you use a fair bit of rapid fix $25 for 5L concentrate.

    You can use fixer at film strength, and it helps too because since you fix for a shorter duration, the fix washes out faster.
