I have a question.
My father had a small 20 gallon salt water aquarium. The fish in the aquarium died about 4-5 month ago. But my father never emptied the aquarium, however the water evaporated about half way. So there was only about 10 gallons of water in the 20 gallon tank.
When I measured the salinity, it was about 1.32 - so I filled up the tank, making the salinity approximately 1.24.
I also added some dry rock.
Today, I bought a test kit and measured ammonia, nitrite, nitrate, PH and Alkalinity. Here are my results:
Ammonia = 0
Nitrite = 0
Nitrate = 200 (HOLY CRAP)
Alkalinity = 180
PH = 8.75
What do these results indicate? Does this mean I can add a fish (after I lower the PH of course)? How much longer should I wait.
The reason I ask is that I didn't really add anything that causes ammonia, so techically the tank should be fish ready.
