I'm running a 10g saltwater QT and the water tests fine except for the hardness. According to my Runbo test strips the water hardness (GH) is 32 d, which is way high. I've researched this and it seems the only way to reduce it is by adding distilled water. I also tested the RO water and salt water that I'm getting from the LFS and the salt water is very high but the RO is fine. So my questions are:
Should I care about water hardness?
Shouldn't both the RO and salt water I get from the LFS have low hardness?
Shouldn't any RO water have low hardness because the RO process removes the minerals that make water hard?
Any help would be appreciated!
