cleaning crew death

[daniella3d]

Hydrometer are horrible and rarely show the real salinity. YOu need to buy a good refractometer. Those on ebay with ATC (auto temperature compensation) are cheap and good.

I suspect either your salinity or water quality is way off or your acclimatation was too drastic.
