crabs & snails dieing what to do

sure there aren't high nitrates in there? anything over 20ppm could start to cause problems....

what about temperature? hmmmmm
 
WOW I didn't know that he posted all these threads for the same question he has a thread on general marine for the same problem, so I guess we can either close this one or the one in the general marine. I don't know if I'll talk to him tonight he works later but I will talk to him and try to explain better on how to use these forums. Just bare with me thanks.
 
I run my tanks at about 1.027 and my inverts are fine so the numbers above are not really accurate.
 
On a FO tank 1.019 is fine. On a FOWLR I wouldn't go lower than 1.022 and for a reef 1.022-1.025 is suggested but some go as high as 1.030 I feel that being too low is worse, it is harder on the inverts IMO.
