Snail & Featherduster Deaths

[kjkerin]

I have a 90 gal reef tank set up for over 1 year. All the water parameters check OK but I am having trouble with snails dieing after a few months. Large feather dusters also meet the same doom. The weird thing is all the natural feather dusters that come out of the live rock are doing fine. Also if you ask my wife I have more than enough alge

This may sound like a small thing but did you check your Salinity I know that when my snails start to become sluggish or die it is most likely my salinity is to high

Even if your salinity is OK, have your LS check it too. Hydrometers are a weird and touchy instrument. Have somebody else measure it, this IS a valid reason why this would happen.
