So I have issues with cyanobacteria constantly trying to overtake my D. neocalidonica seedlings. Unfortunately, they like the warm high humidity environment that they are in (so does cyanobacteria lol). Any suggestions?

If you can't avoid contamination in the first place, this is the only treatment I'm aware of that works: http://www.physan.com/ Keep in mind that this stuff will also kill Sphagnum.

I've tried peroxide before but the cyanobacteria always grows back.

When they grow up, throw some live sphagnum in as top dressing, prevents any algae from growing really. Works well.
