Planaria are notoriously difficult to completely remove from an aquarium. You can perform a thorough vacuuming of the gravel or substrate followed by a 30% water change every few days. Use only conditioned water that is temperature matched to prevent stress or shock to tank inhabitants. Fenbendazole or praziquantel can also be used during this process. Since you are overseas, you can also look for a product called "Planaria Zero" that is supposed to be quite effective. It contains extract of betel nut which is toxic to planaria. Use caution with any medications if you have snails or shrimp in the tank.
