Just to give a little bit more information, we had a 20G tank and upgraded it to a Reefer 350. We checked the parameters and ammonia was a little bit higher and then it dropped to 0. then after 1 1/2 months we decided to switch our corals and hermit crabs ( we dont have any fish) and the parameters were fine too. all of a sudden ammonia rises to 8.0. We went to our LFS and he asked us question about our filter. we told him that we have one cup and one sock where the water goes through first and we washed the sock for the first time after now 2 months. he said that's the reason why the ammonia is so high now. we tried doing water changes, added bacteria (one bottel of dr Timms one and only), we used prime, ammo lock and nothing helps. We checked this morning and its still at 2.0 for days now. All our corals are closed up :(
please any advise what we can do...
