I have two clownfish in my 10 gallon qt tank. I am using a marineland biowheel 100 for filtration. My one clownfish is gasping for air and laying on its side. It appears to have some damage to at least one of his fins. The other fish looks fine swimming around energetically. I tested the water last night and found some ammonia (maybe .25 ppm
). Then I noticed in my replacement water, which I use a 15 gallon rubbermaid container, the ammonia level was considerably higher ( maybe .50 ppm
) and then after 14 hours with the sample in the test tube it went to something like 1 ppm
. Last night I emptied and cleaned my replacement water container and then refilled it with "fresh" water. My many questions:
Why did I get ammonia levels in the replacement water? Should I have used a water conditioner? (I did not) . Should I do now a huge water change and how much? How do I know that all of the chemicals are out of the replacement water container after rinsing many times? ( I used dishwashing detergent to clean it).
