Just curious as to why inverts need a separate QT system? Is it because they are intolerant of meds?Inverts probably wont tolerate the lower salinity. You really need a separate QT for corals and inverts anyway. I keep mine at 1.026.
I do keep salinity low upon arrival with new fish. But I slowly increase it by topping off with saltwater opposed to fresh until I get the salinity matching my DT.
