I will take the chromis back to the LFS
today. I wanted to put them in the main because I thought it may be the phosphates killing them.
I figured the granite would be ok since it was not porous and had large holes in it for small fish to hide but I will leave it out now.
Here are my other readings
I am still puzzled as to where the phosphate could be coming from.
The fish when added were in a school then one would be a loner in a corner only to find him dead in the morning. This moring two were dead. Could it be that the larger ones are terrorizing them? I had two in my QT
previously for 4 weeks and then added them to my main with no problems. Perhaps it is just a bad batch of fish the store received and they have something. Thanks for the response
