I have had my 70 gallon sw
tank set up for about a year. Everything has been fine but lately I have noticed a small level of ammonia in the tank. about 1.0mg/l. My PH
is 8.0 and I have 0 nitrites and 0 nitrates.
Up until recently I always had 0 ammonia. Can anyone help. I have not added any new fish within the last 6 months only two cleaner shrimp.
Thanks very much. The people in this site are excellent and the help is very much appreciated.
