The only reason i want to get rid of them is because I just put new impellers and shafts in my two ac110's and im thinking that snails getting sucked into the filter can damage the the impeller and or the motor housing. They are pretty hard.Just curious why you feel the need to get rid of them.
If they are MTS type, they burrow in the substrate which keeps it from compacting, and help break down detritus and dead plant material producing byproducts can be more easily processed by beneficial bacteria.
Many fish will eat them, and they are a normal part of any healthy aquatic ecosystem.
If you have an overabundance though, this may have to do with overfeeding, or the need for more substrate vacuuming and maintenance.
