Well came back from holiday and a conch dead and just empty shell remaining and next day a urchin dead so needed to investigate little further and check wires into pumps and all that and in sump I had thermoter inbetween baffles and seems came off glass and rattling around hitting glass and smashed outer casing only thankfully as I think red in thermoter = Mercury and grey = alcohol but the red is still incased and still rising / falling in temp as wouldnt like to think what would of happenned if Mercury got in tank and if was enough to kill everything, guessing wouldn't of ended good anyhow.
Saltwater mixing now for wc tommorrow and will run tests on all parameters I got and see what's happening and hopefully conch/ urchin died of old age or got killed by hermits/ pistol shrimp, its not ideal but better than bad water or something bad in water like metals and will kill all my inverts in coming days .
Wonder if a dying torch could affect water enough to cause inverts to die as cannot see one tentacle of my green torch since got back home so guessing it's completely gone.will investigate properley tommorrow.
