Due to the heavy typhoon attacked to Japan on Sep/4/2018,
Items will be shipped from Narita International Airport(NRT) or Chubu Centrair International Airport(NGO),
which normally should have been shipped from Kansai International Airport(KIX).
It may cause delay on shipment. Sorry to have kept you waiting and thank you very much for your understandings.
I think that the value is not accurate. It was initially displayed as PH 4 or less (weakly acidic) in the aquarium, and I thought that there was no problem with water quality. After purchasing the PH meter, I measured it, it was PH 7.5. When measured with tap water, which was correct, the litmus paper was PH.6.4 and the pH meter was PH 7.1. I think the PH meter is correct.
