Ever used bleach in tank to get rid of snails?

This tank had just shrimp and snails in it... tons of snails. It's going to be a beta tank (beta is on order).

I gave up manual removal, moved the shrimp elsewhere, and poured bleach into this tank with the filter still running. I only let it stay a few minutes, as I didn't want it to soak down into the driftwood and substrate too much.

Then I did a 100% (as close as possible) water change, and used 3x the normal dose of prime when refilling it.

It's been a couple hours now, and the snails still appear to be dead. I put the shrimp back in and they are acting normal. The nitrifying bacteria are likely dead, but I can reseed that from another tank. I just hope the eggs are dead. If so, what an easy fix. I only have one plant in this tank though.. I doubt this would be a good idea in a heavily planted tank.

If this works out well, I'm going to use this method on my other tanks after moving my fish to a temporary home.

To see if they're really dead? And because I got out as many snails as I could before doing this. Dead snails are no easier to pick out of gravel than live ones. I pulled out enough to cover the bottom of a kitchen sized trash can before I bleached the tank. In the morning, I will see if the leftover ones survived the bleach bath.

Ooo, I didn't think of taking the gravel out while the snails decay. I can't spread them out outside because I live in an appartment (no yard)... how long do you think they'll take to decay if i sit the gravel in a bucket on my balcony?
