I went to far with it and it got out of hand for a one bedroom condo. I ended up with way to much going on , to much risk involved , could not cool down the apt in the summer with all the halide lighting and equipment. Fear of and having floods was not fun. My bedroom closet looked like sump /refugium city.Both are lovely! What made you stop salt? I've heard that few turn back, but it seems so expensive thats why I have never tried it!
Then back around 2004 we started having hurricanes and I was lucky the first one , switched to fresh and then the next hurricane I lost power for 5 days, that would have put a nasty end to that reef .
The fresh water survived .
