I am using the Aquarium Pharmaceuticals Saltwater Master Test Kit. This kit measures total ammonia.
Tank: 20 Gallon Long Fish Only 26 lbs baserock
Fish: 1 tiny Firefish
Salt: Instant Ocean
When I saw the .3ppm ammonia reading I became worried and started some more tests. I tested distilled water right out of the Walmart bottle and it tested 0ppm for ammonia. I did this because I wanted to see what 0ppm ammonia looked like on the color chart.
I then tested aged saltwater that was in a bucket. It tested around .3ppm for ammonia. This water is the same distilled water just mixed with instant ocean with a SG
of 1.022. I thought for sure this new saltwater would test 0ppm for ammonia but it didnt?
I compared the test color of the fresh aged salt water against my tank water and they are exactly the same. I am very confused as to whether there is an ammonia problem in my tank or not. Is the instant ocean salt introducing ammonia in to my aquarium? Is the salt producing a false positive with my specific ammonia test?
The firefish seems very happy in the meanwhile swimming around and eating very well. I do notice he flashes against the substrate once in a while, maybe once an hour or less.
I bought ammo-lock but am hesitant to add it, also hesitant to do an emergency water change. Thought about taking the water to the LFS
so I can use a different ammonia test. I have ceased feeding since.
What do you all think?
