Okay, so I kind of have a weird question.
We haven't had power so the well water was kinda cloudy when we did eventually get power back 4 days later. So I boiled water to use for the 100% water change so no funky things could get in my fish tank. I tested the water parameters before I put the boiled water in my clean tank, the pH was normal, but when I tested for the High Range pH it was an 8.8, a 1.4 jump from when I tested the old fish tank water the night before. So I got some tap water and tested pH and HRpH, pH was lower than the 7.6, more like a 7.0-7.2 but the HR was back to 7.4. So I just used plain tap water for water change, added some conditioner & clarifier and everything is fine.
What in the world happened? I normally use just plain tap water w/water conditioner for water changes and never boil it. Why did the HRpH shoot up so high and pH stay the same after boiling? I'm so glad I tested the water first...Poor fish would've died of shock.
