If you search for the term "conductivity" in this group will you find
some good past posts on this topic. People seem to keep their systems
at around 300-500 uS. I use Instant Ocean in my system and fill a 15
ml conical tube to about the 2 ml line for every 9 liters of DI
water. And I replace evaporated water with pure DI water. That seems
to keep my system at about the correct conductivity.
The big issue I had when starting my system was a crash in pH down
below 6.0 that started to kill off my fish. I now place bags of
crushed coral in the bottom of my sump, which keeps the pH constant at
just above 7.0. I have been replacing the coral every year. The
Zebrafish Book does not mention using coral or pH stabilization, but
you can also find a lot of information about it in this group.
Hope that helps,
