The problem of using Prime with no ammonia is that it consumes massive amounts of O2. So now you have bacteria going crazy (clouding the water) that are consuming lots and lots of O2 and you just added Prime which will lower O2 even more. This is why I suggested not adding it unless you actually have a problem with ammonia.
O2 deprivation?
Total guess. If snails and other bottom dwellers are OK then I have no idea why starfish would die.
Did they just stop moving or did they start to disintegrate (could be osmotic shock).
Sounds like a sudden decrease in salinity. Doesn't sound like that could have happened in this scenario though.
I'm hoping you mean that's the specific gravity and not the Salinity.

Hmm, always wondered what the other numbers meant lol
Look through the eyepiece again and look at the other side of the scale. One side will list "d 20 20" or something like that. That scale is not an accurate reading of Specific Gravity since refractometers do not measure S.G. Ignore that side.
The other side will list something like "0/00". That is the Salinity side of the scale. On calibrated ATC refractometers this salinity reading will be highly accurate.

I'm glad I'm not the only one.
