Inverts help

[Lucastank]

My parameters seem good - fish and corals doing well. Have fk
Lucas evo.

My sand inverts all good but any snails that take care of the glass, seem to only last a few weeks/months.

Not sure what I am missing and or what could be causing them to die.

You should provide more details (eg, specific parameter readings, picture of your tank, etc) if you want to get sensible feedback.
