While back Lorry and I had a discussion about pH balance of tap water vs. bottled water. She thought that our fishes are having gill flukes due to acidity of water. Also, I shouldn't drink tap water since it has high concentration of ammonia and just general 'poop' in it. I doubted these allegations and we end up doing some tests. Bottled water turned out to be close to 7.0 however tap water was basic. I thought it was actually good because being alkaline would make it less reactant to pipes and lead. Following are the pictures of our tests. The ammonia level tests were either in-conclusive or just can’t remember what happened.
