Actually most fish acclimate just fine to those types of readings. What type of plants and lighting do you have if your considering CO2
? Also what is your stock?
Personally I wouldn't be concerned unless your keeping more delicate fish or plants that really need softer water. I have tap water that is very close in numbers to yours and in some of my more delicate fish tanks such as my 55g and 24g nano fish tanks I use RO
water to cut with my tap water during WC
's so I can keep my kh
/ph where I want it. But this is an exception not the norm.
