Killing duckweed

[seangee]

Sorry I am looking for solutions not offering them
I am having yet another go at removing the scourge from my community tank. Its actually going quite well. I added a surface baffle to separate the amazon frogbit and if I ever see a speck of duckweed in that part of the tank I get rid of it. In the rest I removed the HOB and airlines so there is nothing for it to stick to and have been netting regularly. I have now got to the point where I only check once a week and there usually isn't any. Not declaring victory just yet because I have been here before
My question is making sure there are no rogue specs remaining on the net. I know you only need to let one dehydrated spec back in and the whole cycle starts again. Obviously I clean it visually but am at the stage now where I would like to be absolutely certain. I am thinking ...

1. Dunk the net in undiluted bleach after every use
2. Dunk the net in boiling water
3. Dunk the net in peroxide.

I know that #3 will work but its not my preferred route as peroxide turns to water quite quickly so I would regularly have to buy more. #1 and #2 are readily available and easy. Would either of these be sufficient to guarantee anything I miss can't come back to life?

On the long If you are at this stage you need a more stable compound that does not vent rapidly. But 20 for 1 bleach is good enough.

Sodium metabisulfite and potassium bisulfite are both extremely stable and can be left open air for weeks and still kill everything dipped in and rinses like a marvel.

It's corrosive, so don't forget the net too long in. It's what we used in large operation where nets go everywhere.

Dipped and rinsed after uses, then dipped and rinsed before uses.
