Even though snails can be a good addition to most aquariums, their numbers must be kept in check. There are also certain species, including the abovementioned Pond snail, that need to be eradicated completely if you keep a planted aquarium. Snails are especially prone to multiply rapidly in hard alkaline water and the aquarist must therefore pay special attention to their numbers in such aquariums. Snails need the minerals to form their shells and too soft and acidic conditions can actually cause the shell to dissolve and leave the snail completely unprotected from predators.

Pond Snail – You would be hard pressed to find anyone who actually wants pond snails in their aquarium (unless they are breeding them for Dwarf Puffers or other similar fish). While they may serve some purpose in outdoor ponds, they are considered one of the worst pests in home aquariums. Killing Pond Snails | My Aquarium Club

Would you believe ponds? They grow wild (but not too wild) in Iowa (we're a bit on the tame side). However, no one goes out in the wilds of Iowa in search of pond snails. And very few aquarium keepers in Iowa care to purchase them (certainly not puffer keepers). Most pretty much depend upon the vagaries of fate Like the egg blobs in the picture above. Each blob contains a couple dozen potential little physas. That's one reason these guys can rapidly overrun your tank. Smaller pond snails can sail across the top of your aquarium -- not above the water but just under the surface -- hanging upside down. You'll notice this sometimes when you have flake foods floating on the surface. If your water is turbulent or has a fast current, you're less likely to see this behavior. You might also want to know that they inhale oxygen at the surface.Most sources say pond snails eat algae. But I've found lots of them in algae-covered tanks. I think they eat mostly fish food. Aquarists that overfeed their fish can thank their pond snails for saving their fishes lives. Without the snails they would have cloudy water at best and toxic water at worst. Feed lots of extra food and you'll soon see lots of snails. Physas will also eat dead fish, some vegetables (especially zucchini), feeder blocks, and your aquatic plants.A lot of fish keepers might have faced this pond snails problem in their fish aquariums or ponds, where the population of these little pest nails exploded despite the best effort to control it. These little pests are hermaphrodites. It means they are both male and female in each one of them. Any two of them can mate and both can lay several dozens of eggs. They can multiple quickly into hundreds from just two if the condition is ideal. The eggs of pond snails can come with plants, or decorations while remain unseen. Sometimes they can come with the water. Their young can swim. Their adults can do “submarine” trick by somehow managing to get enough air in their shell to rise directly toward the water surface or to a higher place in the aquarium. For many new fish keepers, it is a pain to have pond snail and it might seem they are impossible to get rid of. Forget those snail killers in a bottle. They usually just stun pond snails. And if they do kill them, you need to vacuum their little carcasses out before they pollute your aquarium. Then cut back on the excess food you were feeding your fish. Crushing your snails works better than the commercial poisons. The little guys you can crush with your bare hands. The larger ones not so much. They slice your fingers. Use the rubber handle of a screwdriver. If you use a plastic handle, some of the snails sorta slide (whoa, inadvertent alliteration) out of your deadly "crushing machine."Second – Introduce predators of pond snails.
You should avoid using any chemical means to get rid of the pest snails. We generally must avoid the use of any chemical in our aquariums other than water conditioner.
So the natural way is the best way to fix this problem without any ill effect.
