Some change water frequently.Hi I’ve been told change 25% of water every 2 weeks figured why not look into automatic water changes.
It’s OK to do that.
But it gets expensive and Iam not convinced in the worth.
I found it easier and cheaper just to replenish the evaporation,
the 3 majors, and the trace……and keep the water.
A few times a year, I change 10%, not sure why,but it feels good.
I just dose everything being consumed.
