Just bought nitrite test kit (only previously testing ammonia on 6wk old tank with fish, so thought need to test nitrite as well).....test result came back at zero - obviously I am pleased but a little sceptical - is there any way I can test that the kit is working (I understand if they have been on the shelf a long time the accuracy can deteriorate)
thanks
