So first I am a beginner at this hobby, so please bear with me. I am going to outline as much info as possible to help ensure everyone can provide as much help as they can. 5/29 - Setup new tank, cleaned all inside components, filled with water, turned on filter, used tap conditioner. 5/31 - Tested water, High ammonia , used API ammonia Lock 6/2 - Tested water, High ammonia , used API ammonia Lock 6/3 - Used PH Lock 7.0 by API to bring pH down 6/4 - Tested water, High ammonia , used API ammonia Lock. Also added 5 Zebra Danios 6/5 - 3 Danios Died 6/7 - partial water change roughly 20% used water conditioner 6/8 - 1 Danio died, tested water high Ammonia. did nothing. 6/10 - Final Danio Died - Read about Seachem Prime, bought 6/11 - DId partial water change, added Seachem Prime & Stability 6/12 - Added Seachem Stability 6/13- Tested Water still no change in water results. Added Stability I have a 29 gallon tank, a 150 watt heater a Aqeoun filter, that filters 200 gallon per hour. I use the API freshwater test kit and follow all directions step by step. Attached in a spreadsheet is the test results form each day for all tests. I need to know should I be seeing changes now? If so, what is going wrong, and do I need to do? I want to do this right and also not kill any more fish if possible.
