I have used bleach, potassium permanganate (Jungle Brand "Clear Water"), potas permag crystals, and malachite green ich treatment.
All of them work but bleach fries anything with finer leaves, potassium permanganate crystals are like $80 a quart around here, malachite green works great but it dies your plants even greener, and you have to use a lot of the Jungle Clear Water stuff but it is cheap.
For ease of use and price, I use the Jungle Clear Water because it is like a dollar a bottle and it is easy to make a solution as strong or weak as you want.
Potassium permanganate will NOT kill encysted worm eggs or insect eggs so be careful when transplanting wild vegetation.
I've got a tank on my deck crawling with bugs and worms and I hate it. Tubifex worms are SO GROSS!
