Substrate in hospital tank

[Buccaneer]

A freshwater bath is not going to directly kill a fish but give instant relief from the parasites already clinging to the fish which in fact are stressing out the fish... if a fish dies from a freshwater bath IMO then it was doomed to begin with ... as to hyposalinity it is probably the least stressfull method of ensuring the ick is eliminated ( Copper is rumoured to damage the intestinal tract of fish ) A refractometer is I think essential to this hobby or at the very least regularly check your swingarm hydrometer against a Refractometer ... maybe we should at our reef meetings ensure that there is at least one calibrated Refractometer for those that want to check their swingarm hydrometers.


I have a foxface that every now and then gets cloudy eyes and the occasional spot ... no other fish in the tank gets spots or cloudy eyes ... I feed garlic with their nori every other day and recently started sprinkling their mysis shrimp with Beta Glucan to improve their immune system ...

Although a stable old tank would be ideal it is not always feasable and alternate methods need to be explored.

Cheers
