The man who fitted the filter said ALL the chemicals get taken out and it is as good as bottled water.
he said no water is completely clear not even spring water.
It´s one of the best you can get so I do not think the water is a problem.
I cannot understand why Pickle seems ok though, she´s out rummaging around the tank, digging, then goes in the water.
Goober has stolen her house though so she goes into his.
Could it be he dislikes her?
