Hard Water / Lenny
just tested the tap water straight from the tap before adding dechlor (i found the Prime so i bought it) GH = 120 (moderately hard water) KH = 80 mg/L PH = 7.4 Nitrate = 0 ppm Nitrite = 0 ppm Ammonia = 0 ppm
friday test results from the tank are PH is 7.2 Nitrite is 0 ppm Ammonia is 0 ppm Nitrate is 5 ppm KH is 60 mg/L GH is 220 ppm (very hard according to the hagen chart) water temp is 74
Today from the tank: PH = 7.2 Nitrite = 0 ppm Ammonia = 0 ppm Nitrate = 0 ppm KH = 60 mg/L GH = 220 ppm water temp is 74
KH x 0.056 = 336 gH° KH x 0.07 = 42 Clark H° KH x 0.6 fH° KH x 1 = 60 hardness° KH x 0.02 = 1.2 mEq/L
what could cause the hardness of my tank water to change ? i have not added or removed anything?? both filters now have the bio max, particle filter and fine particle filters should i soften the water or leave well enough alone? if i need to soften the water what is the safest way to do it without stressing the fish and changing the PH ? i have to get ready for work so i will check my emails just before leaving and again tonight when i get home before doing anything
