Hi everyone! Still working on getting my 75 put together. Today, I tested the water that is in the tank, and noticed some inconsistencies. Our water (well water) comes out of the faucet at a ph of about 6.6, and 6 degrees of both KH and GH hardness. The water in the tank is testing the same for the hardness, but the ph is 8.0. Does anyone know what might cause this? From what I understand, usually soft water has a lower ph. Tank info: sand substrate, granite rocks and driftwood for hardscape. Filter is a Sunsun hw304b with Matrix, foam pads, carbon, and polyfil. No fish or plants at this time. Nothing done yet to cycle the tank. It honestly baffles me because of the driftwood...I would think the ph would be even lower than what comes straight from the faucet, but it's not!
