OK, just used test strips for Nitrate, Nitrite, Hardness, Chlorine, Alkalinity, pH. I keep Dwarf Puffers and Endler's Livebears. Everything came back pretty much fine. Nitrate was 20 ppm (mg/L)
Nitrite was 0.2 ppm (mg/L)
Total Hardness (GH) ppm 300 THIS IS WHY I POSTED
Total Chlorine 0
Total Alkalinity (KH) ppm between 80 - 120
pH - 7.2 to 7.8
1) why is the water so hard? i do add fresh water aquarium salt to prevent disease, electrolytes for fish, etc.
2) Should I worry about the Total Alkalinity and pH?
also I add Aquarium Pharmaceuticals Water Conditioner.
PS: I am also worried about because I have about 20 endler's fry
