okay i think im using the wrong water tests with my conditioner, im using xtreme water conditioner and on reading the back it says use a salicylate (indolphenol) type total ammonia test kit. for dissolved oxygen testing use either a DO meter or an indigo carmine test, well im using api water tests, this might be giving me false readings, so im going to switch to seachem prime do my water changes with prime and then see what my readings are, i think the conditioner has to do with my problem, xxxxx
