Why is PH rising ?
I have a recently set up tank that the pH is climbing to 8.2 within 24 hours of adding water. Water from well goes in at pH of 7.8
I tried adding Seachem pH buffer, got tank water to 7.2 and 24 hours later it was up to 8.0.
Here are the specs:
Newly set up 9gal Fluval Flex, stock filter and lighting. Added some mature filter media from a friends tank to filter. Set up 10 days ago.
I don’t have gh/kh test yet, but water is typically pretty hard due to area having limestone
Well water ph from tap: 7.8 pH
Substrate: CaribSea naturals sand
Hardscape: Driftwood with slate base (slate under substrate)
Plants: Java fern, moss, subwassertang, Buce...
No fertilizers or CO2 used.
