I use the Wardley pH test kits. I have the high range and the low range kits. The high range kit says it's for saltwater or brackish. Does it just say that because SW and brackish need higher pH than freshwater? I'm using the high range test on my freshwater, and I wonder if it's accurate in FW.
When I use the low range kit, I get 7.4, but my water is darker blue than the 7.4 color chart, which makes me think it's higher than 7.4. When I use the high range kit, I get 7.6. So I'm wondering which reading is accurate. I think the 7.6 reading is probably more accurate, if the high range kit is accurate for freshwater.
