I am contemplating switching from spring water to tap water for my fish to save money.
I have a 5 gallon filtered tank with plants.
I just tested my tap water...
Total Hardness: Soft (75ppm)
Alkalinity: Moderate (80ppm)
pH: "Neutral" (7.2)
Does anyone know if there is a filter that can make it into Spring water?
What is the best way to make it safe for the fish? (How much of X per gallon?) How should I introduce him to the new water? Anything else I should know? Thank you!
