    Hey gang,

    was just wondering about something, i was fortunate enough to be be given a complete setup of Pure Reef Supplements, like the whole lot, by Reefer and Midasblenny at reef meeting end of last year. i used em while i still had my nano running.now im setting up my cube. the question is this, seeing they hav been standing for like 6-8 months now. will these additives still be good to use on my new system even after standing for so long. or do they go "off" after a certain period of time?

    TIA
    lata

    Additives should be fine indefinitely.

    Worst case is certain additives might lose a bit of effectivity (i.e. not as concentrated) but they will not have any negative effects on your system.

    Yes, as long as no one has tampered with it in the meantime

    Test kits do expire and will usually read negative/low if they are off. So you may be testing for nitrates and pick up nothing and so you think all is well. Meanwhile the test kit is expired.

    I'd stick with the expiry dates of the manufacturers. A couple months over expiry date shoud not be too much of a problem either.
