    it looks like this ( attached photograph )
    you take your spent fixer, stick it in something like
    a lucite shoe box you get at the dollar store
    you drop the magnet in it, plug it in, and wait for the
    2nd light to come on .. then you dispose of the fixer ..
    ( it still has silver in it ) ...

    The cathode reaction is the reduction of the Silver in the thiosulfate complex

    The anode reaction is the oxidation of the sulfite ion to sulfate ion which keeps the used fixer from being reusable

    Jnanian, is it safe to dump this remaining fixer which still has fixer it it, down the drain? If so, does it make any difference if the drain goes to a septic tank? TY

    it has around 50 parts / million of fixer in it and should not be dumped down the drain. federal guidelines say it has to be less than 5 parts / million
    and of course different cities, towns, villages states &c have stricter or not so strict requirements. if one uses a trickle tank has the ability to get the parts / million low ( less than 1 low )
    it will never reach 0 ...
    i wouldn't put anything in the septic tank, kodak also has this perspective, the silver will kill off beneficial bacteria that will eat the contents of your septic tank.
    i can't speak about where you live and what the laws are .. but your local water / sewer commission might be able to help ... or recycling / househole hazmat day ...

    sorry if i am not helpful, i can't really suggest much, other than get the silver out, and don't dump it down your drain ... and to ask someone local who knows the answers.

    "trickle tank has the ability to get the parts / million low ( less than 1 low )"

    So, if using a trickle tank, its a fraction of what the silver magnet is, but still to high for a septic tank?

    Thanks for all your info.

    smaller, 2 gallon trickle tanks soon to be available

    i am in touch with another company that has 2 gallon trickle tanks / media buckets and test strips
    that will be sold as a single unit. i realize the 3.5 gallon bucket might be more than what some folks here
    need to use, so i did some research and found a company that could supply me ( and me to you )
    smaller tanks/buckets that do the same thing. they will cost a bit less than the current 3.5 gallon tank i currently offer.

    i am waiting for a quote from the sales department as i type this post.

    thanks for your interest in doing your part to soften your silver footprint.

    Hi, I was wondering if you had any of these units for sale at the moment. I was wondering if you could give me a quote for the cost of the unit and the shipping to New Zealand.
    Regards

    sounds to me like that was silver-sand / silver-flake
    which is close to pure silver
    oh well, ... at least you gave it to hazmat !

    i thought i posted the new price in a different thread ..
    the 3.5 gallon tank is now 216$ and the 7gallon tank is 256$
    it ships in 2 boxes and the last time i sold one the shipping was
    between 20-30$ depending on where it was going .
    the other company raised their prices in the last year
    and they are not any smaller or any cheaper ...

    Rather than buy something for silver recovery, why not just get an old empty paint can, drill a hole in the bottom and stuff in a ball of steel wool. Drain all your spent fix through this and occasionally remove the steel wool and scrunch it up over some newspaper and the silver will fall off.

    hi clive

    i did sometihing like this for years, also used copper flashing before it became too expensive.
    when you use the steel wool or copper or whatever it is you are trading ions with
    it ends up being a sludgy mess.

    YMMV

    John, sorry I forgot to mention that you do the scrunching when the wire wool has dried out.

    No it is not, as it is dry silver.

    i would not recommend anyone scrunch up dried steel wool like this
    the dust and sludge plume is not good to breath ...
    a trickle tank is sealed and the "stuff" stays inside the tank
    so you don't have to deal with breathing in stuff that isn't
    good for one's health.

    Hi John- I have a question for you...Does the fixer have to be really totally spent before using the magnet in order to not burn it out? Also, does it matter if the fixer that you would like to treat with the magnet has been sitting around for a long time (A few years)? I think I have seen these things discussed around here over the years but cannot seem to find them. Thanks!

    hey there

    yeah the fixer has to be well spent. it has to have about 50-52 parts/million of silver in it...
    if you know whatkind of fixer it is and have some that is unused/fresh you can see how long it takes
    to clear a piece of film leader and see how long the old stuff you have takes. if it takes 2x the fresh fixer's clear time
    you are OK, if not .. it doesn't have enough silver in it.
    hope that makes sense -
