What kind of snails, worms, and algae? Can you ID from pictures here and around the 'net, or post pictures and/or descriptions if you can't ID them?
Some types of algae are normal for new tanks, and disappear on their own. Others indicate a problem with your tank setup; which is a useful indicator, not just a nuisance.
Some types of worms are fish food and will disappear when you add fish.
Most types of snails are actually beneficial, although some reproduce to nuisance levels. There are mechanical, biological, and chemical ways to control or eliminate them.
Planted tanks are challenging and require problem solving skills. If that doesn't fit with your lifestyle or goals, perhaps a fish-only tank is the right choice.
Otherwise, address each problem individually. Each problem is a necessary learning experience and stepping stone to being successful. If you just give up and nuke your tank, you'll learn nothing.
