You can tell that you need do dose more when algae starts growing on your glass again.

My experiences are with commercial and personal tanks. In all cases, these are ULN systems and the filtration is able to keep up with the die off. with that in mind, you don’t want to hit your tank hard with a strong dose up front. Rather, you want to slowly introduce this medication. It will absolutely work provided you don’t do this too quickly. Your first sign that the CP is working is that you stop having to clean the glass so often. All algae dies off, snails and worms die off too. If you have a mature tank with lots of worms, then they are going to increase your risk of an ammonia spike.

Now if you detect ammonia with a test kit, then dose amquel. Both products are compatible.

So the truly difficult part is taking this slow while knowing it will work as long as the die off doesn’t all happen overnight. Since I don’t know your tank, I would advise to go ultra slow with 10% of the typical dose added to your tank once per week over a period of up to 10 weeks. The first three weeks you will know if your filtration system can handle the snail the die off. Just keep dosing 10% per week eventually it will kick in. You probably won’t even need to get up to go the full 10 weeks. When all the snails are dead, just leave the med in the tank for another month and enjoy the algae free and snail free look of you new tank. Then introduce carbon and water changes.

To minimize risk, I would not turn off your skimmer at any point and I would also plan to change out your filter socks every couple of days.

Note that the commercial (LFS) tanks and personal tank are all relatively new tanks where CP was planned for from the beginning. The LFS tanks are given small maintenance doses every two weeks or so when the glass starts to show an algae haze. If your tank is mature with lots of worms then you could have die off just like if you dosed prazipro in your DT. Both are safe with caution but you have to go slowly. Both will kill all the worms in your tank and ammonia may become an issue so tastyfish’s story is something to be concerned about. Manually remove all the regular snails and worms you can find with a fish net going through the sand.
