Any idea how much salt one can safely add without affecting plants in RO-like
water? How would you know if you've overdone it?
I am wrestling with trying to keep highly inbred guppies alive, they seem to
need the salt, and I have been adding about 1 teaspoon to my 25 gal a week,
which is nowhere near enough for the fish! So far the plants have been fine;
I change 50% water weekly, sometimes also a 30% change mid-week, as I have fry
in the tank and it can get a bit over if I feed too heavily.
