I think you need to ask yourself what a "snail issue" is.
If you can't stand the sight of them, and you haven't even started yet, the easy route is to keep them from getting in the tank. There are literally hundreds of threads you can search on how to best treat plants for unwanted snails and their eggs.
If you fear your tank will be overrun by legions of snails, then simply take steps to maintain water quality and simply don't feed more than what your fish will consume in any single feeding. Over time, their numbers simple reflect their available food supply. Adding more fish and inverts to eliminate them only adds to the tank's bioload that already is stressed by uneaten food being processed. So that if you eliminate the snails your now left with the problem of uneaten food and more fish adding to the overall bioload.
