Question
I always had problems with snails in my aquarium. They reproduce faster than I can remove them.
Last time I had such problem it was solved by restarting my aquarium: took all the water of it, throw away plants, sterilized stones and wood with boiling water, cleaned the glass, and saved some water treated with chemicals. Then began everything back, put my fishes back...
If it ever happens again, how could I fight back those snails without using aquarium ?
Answer
One piece of advice I've seen is to use bait to lure the snails out, and then physically remove them. This may help you keep up with them.
Methods of baiting range from simple (put a large piece of lettuce in your tank, turn down the lights, and wait a few hours) to more involved (build a small "trap" by placing food the snails will find attractive in a container big enough to hold a bunch of the snails, but too small for your fish to get into to eat the bait).
Another popular non-chemical option is to find fish that eat snails, and add them to your tank. Loaches appear to be good choices, if available; especially the clown loach or yoyo loach.
Puffers are also mentioned, but they can be aggressive towards other fish, so probably aren't a good solution.
You can also help keep their numbers in check by cutting down on their available food. Avoid overfeeding your fish, and periodically clean your gravel. You can also add algae eating fish, such as sucker fish (be careful which kind of suckers you get, as some can grow quite large, and therefore require a larger aquarium to ensure their health).
I found some good overall resources/guides for snail control:
