That will increase the snail population but I've found that a snail "problem" can arise no matter what. Snails will eat anything, including fish waste. They'd rather eat plants or even fish food, but it's not necessary for a problem. I found snails in a tank that had been abandoned for 6 months.
Another alternative to remove them is to put lettuce or spinach in the middle of the tank, leave it over-night, then remove it in the morning. A good majority of the snails will have congregated on the leafy vedgie and can simply be removed. Then try to crush any egg clusters you see. A good fish to take care of the problem is prefered in my opinion, but there are options.
