I've had a high PH problem - its been around 8.6ish or more. I realized it was probably my tap water so I went out an bought 20 gallons of RO water from Walmart. When I tested that water the PH was still around 8.5? I did a 20% water change and my PH is still 8.6.
What can I do to get the PH down? Its the only measurement thats keeping me from having a safe tank.
