Safe Nitrate Levels
My tank is cycled now and the ammonia and nitrites go to zero overnight after adding ammonia each day.
My nitrates are at 20ppm and holding.
PH is 6.8
I have done a 50% water change the last two days that brought the nitrates down.
What is considered a safe level of nitrate for fish and shrimp?
