Technically, yes: it's possible. The measures are, essentially, independent of each other.
- What is your water source (softener or RO involved)?
- did you verify that the API kit has not expired?
Local water association and owner of our 33,000 acre reservoir is who provides the (treated) water. Nothing but Prime used before it goes into the tank. The API kit is good till 2024 I think. Iím about to test it again tonight to double check results and then test the tap also.
Yesterday was total user error! Being much more cautious about the instructions tonight, i find that I basically have nothing in the tank water for minerals. GH takes 3 drops to really start to see green but at 1 drop the water is starting to shade that direction, definitely no orange. However, the KH test was a total bust yesterday! One drop properly mixed into the tube gets me blue water. So. Nearly no minerals in my water. Is it safe to assume I need to raise the hardness and the KH at least SOME for my fish and (soon) snails?
Tap water shows the same results.
Tap pH is in the 6.8-7.0 range which is consistent. My last water change was probably 4 days ago and the tank pH is up to about 8.0. I donít know what it would get to if left alone, but the tank definitely creeps up from what the tap puts out. So the tank is basic and very soft.
Neon tetra, mollies, platys, a barb and a rasbora, otos, getting snails. Plus several live plants. Very quick research makes it sound like I need to probably lower the pH some but raise the GH some. And maybe the KH too. What say these experts?
