Cleaning tank with sand

Invasive snails can be controlled, even eliminated with careful tank management. Eliminate their food supply and they go away. It is easy to do especially since you only have artificial plants.

Eliminate their food supply. Since you have multiple tanks, I recommend starting with just one tank until you get the hang of it.
Sparingly feed your fish. A few small feedings are better than one or two large feedings. Make sure the fish eat everything you give them.
Keep the tank algae free.
Do you have live plants? If so, remove all old or decaying leaves. Quarantine any new plants.
Keep the substrate clean as you are doing.
Manually remove as many snails as possible.
Make sure to completely clean anything that is used from tank to tank such as fish nets.
Again, concentrate on just one tank at a time.
The last thing I recommend is using any snail eating fish (or snails) to control snails.
