I use the 6% hydrogen peroxide. Good experiences are made here in the summer months. Less deaths in the hot season reported in forums.
Most people have come to agree that increased oxygen levels in Taiwan Bee tanks are highly beneficial.
They are just discussing what the difference might be between using airstones and using these ceramic things to introduce pure O2.
Either way, thank you for sharing.
What little German I learned in school was a LONG time ago (I think that y'all may still have been Prussian at the time...might have even been before the Romans started fighting the Germanic tribes).
I would feel like a total geek if I had any of my German friends try and translate any of this stuff for me so it is always appreciated when someone shares more detailed information on German shrimp keeping with us English speaking folk.
