with your float valve do you leave the water on so your tank is always full?
I only ask this because i loose a lot of water every week due to evaporation.
if so how do you know how much conditioner to use?
i have been thinking about doing this for a long time but not knowing how much conditioner to add has always worried me
I don't leave the water on , I used to worry about an accidental flood all the time. I have it running to a closet where it's connected to what used to be my R.O. . I just removed the R.O. membrane and have the 3 sections of the filter in use with filters and carbon . I usually top it off once a week in between water changes by adding a little prime . When it was R.O. water I left it on all the time to top itself off.
