i just found some phosphate remover that i lost for about a year(stored away always sealed with some fish supplies).. how long does this stuff stay good for?? one was opened and used the other is new but was not sealed on the inside.. just wondering how long products are actually good for.. i wouldnt want to use it, just to find out things like this can go bad.. like can carbon, ph and alk booster, along with some kalkwasser.. can any of this stuff expire??
