Medicine to eradicate snails in fish-free heavily planted dirtied tank

[Firestorm_1976]

What is good anti-snail medicine for a heavily planted tank (that currently only has plants, no fish) to nuke what looks like baby snails that might have hatched from plant introduction? Something that reliably kills snails but has no negative effect on plants and does not accumulate in the seams of the tank (so, after several water changes will not be toxic to future desirable snails)? This young 29-gallon (started 12/12/24) is also battling with cyanobacteria (I tried Ultralife Blue Green Slime Stain Remover, but sadly it did not work). So, if there is a medication that can help with both snails and cyanobacteria, that would have been even better (although snails do take priority, and I want 100% of them gone (so, not something like Dr. Tank - #7 Snail Remover that claims to remove only 90% of them). I am at a point of giving up and wanting the rehome the tank . Please help!

I have assassin snails in my other tank, but don't want to introduce them to this one.

There are copper-based additives that are deadly to snails. I have never used them or know brands. They will likely affect plants as well, so a pickle.

Be careful. You aren't asking about medicines to eradicate healthy problem creatures. They aren't a sickness. You are looking for poisons, and poisons are fairly indiscriminate in what they kill.
