I have a tank which i cleaned really good after its days as a plant tank... Now i think i killed all the snails inside the tank but I'm afraid of the snails that are inside the filter... If i was to blast the tank which has no fish inside with a load of salt and after a long time lean out the salt tell their is no snails/bac . I don't need bac or anything like that yet cuz i have sponge filters ready to go in another tank plus i can start a fresh cycle after i run a salt cycle to cleans of snail/eggs... thanks....
