shirmp and hermit >>> are dead

yeah i think salifert has a Cooper test kit. Your LFS may test the water for you for a small price considering you dont really test for copper regularly.

did you buy your tank brand new or did you get it used? traces of copper could have leached into the silicone.

whats your salinity and PH?

whats your salinity and PH?

salinity 1.021 , ph 8.0

Ur salinity should be around 1.024 or 1.025. This could be the issue but ur salinity is technically on the low side of acceptable limits.

Did u ever medicate ur tank when u had fresh water fish?

[jhoepopoy]

yes i did medicate my tank... u mean my salanity is lower??... that's why now it make sense for me... thank you...

your salitinity should be higher but that wouldnt kill your hermits, so i would still test for copper

[jhoepopoy]

thanks cathyg_99 appreciate it...

[cathyg_99]

my only other thinking is there just killing each other... i have two left out of oh... 30 even with extra shells they still killed each other but i dont know why your shrimp would have died...


is it a cleaner or a peppermint? if its a peppermint it could just be a molt, i get a little body and cant find him for months so i assume hes dead and he pops out

Although salinity should generally be kept around 1.025 - 1.026, I don't think that should be the reason your inverts are croaking. Most LFS systems are kept at a lower salinity than our tanks at home. This is why acclimation is fairly important. These critters can handle a pretty good range of salinity, provided the change is gradual. A very quick change could be a problem though, this could be caused by a massive water change where the makeup water is significantly different than the system water.

You say the tank has been medicated. With what? That might be something that could cause problems. I believe most hobbyists use a quarantine or hospital tank to medicate their livestock if that's feasible.

Like Mike asked what did you medicate your tank with? Could be the issue.

Also like mentioned your salinity needs to come up, your corals can suffer. I usually tell people to just do top ups with pre-made salt water, brings it up nice and slow

Most people forget that if you're measuring specific gravity you have to account for the temperature of the water too. I find this gets left out very often. I personally prefer the calibrated refractometer method now, I don't think I could go back. With hermit crabs I wouldn't be surprised if they were killing each other as well, they're pretty expendable.
