so I found a bladder snail in my filter for my goldfish tank. the filter has 2 hob compartments but they both had 15 bladder snails eggs each. I scrubbed it and put the filters back in but there's still some tiny snails in the filter material. if they end up reproducing will it be the end of the world?
I've only found 1 in my tank and then scrubbed the tank very well and haven't found any snails or snail eggs in the tank itself.
will a population of snails in the filter compartments be bad or it it ok to let them do their snail thing?

They are pest snails and they can take over your tank if you don't keep their population in check.

They are not a bad thing. They can actually indicate whether you are over feeding. When the population increases, you are feeding too much. Pick them out as you seen them. Once you have them they can be a pain to completely eliminate. But it is possible. It just takes awhile.

Don't over feed.
Bait them out with veggies.
Pick them out as you see them.
Considered some assassin snails. The thing with these is they will reproduce too.

If these are the snails that usually come in on plants, then I have managed to get rid of them.

Every morning I would lift the lid and squish all the snails that had come up to the surface during the night. My fish would wait for me to drop them into the tank - they loved them after I had squished them.

I also managed to vacuum a lot of them from the gravel.

After a couple of months of doing this faithfully every day they were gone.

"Pest snails" Can't take over a tank without help from the fishkeeper.

The population will grow to the level your tank will support. Then it'll level off and maintain. Not a bad thing, especially in a goldfish tank. Snails eat fish poop. They actually reduce the overall bioload as they further breakdown solid waste.

A good way to keep the population "in check" as it were is to be very careful not to overfeed, and scoop out any food that hits the bottom. If somehow your population grows more than you'd like, pin some boiled veggies in a glass jar and leave it in the tank overnight. In the morning, the jar will be full of snails and you can remove it and dump them out.
