I’ve always used the fresh
RODI water I purchase from my
LFS for my tank with danios. However, I have limited water jugs and also need the
RODI water to top of my reef tank. I’m anticipating not being able to go to my
LFS due to the corona virus spreading in my area. Should I just do water changes with tap water for the danios? I do know it has no chlorine but don’t know the
TDS of my tap water.
