Yes, late last week was a couple days of sadness when I realized my outdoor barrel of baby White Clouds got wiped out by my changing far too much water and too cold. I lost about 60 fish. :crying:The more I learn about aquariums, the more I learn about everything. Plants and fish suffer the same as people. We get micro, or macro sufficiencies and deficiencies.
