Potassium permanganate is great, of course I'm not using it for tissue culture plants, they don't need dipping in anything.
I don't dip plants scared of algae. I just don't want any bladder snails, any other is ok, but those are eating plants so a big no for them. For now - dipping in potassium permanganate works like charm (and I saw live bladder snails on plants before dipping once). It's not mandatory, but I like to keep plants clean of them.I think it's near impossible, no I'll say impossible to keep you tank sterile of spores, etc. that will cause algae. It's your conditions that bring it out. I never dip anything ever.
You could certainly eliminate some, but point being you just can't eliminate everything. Snail eggs, etc can be in a drop of water that enters the tank from another source.I don't dip plants scared of algae.
