3% hydrogen peroxide safe for...

[KnightlyBuzz]

I’ve used 3% hydrogen peroxide (4/1 ratio tank water to h2o2) to dip a couple of chalice frags for 2-3 minutes to kill algae. Can I do this for a small toadstool, devil’s hand and duncan frags? Thanks.

yeah, 3% is waaaay safer than food grade...And yeah dip, not dose:

Aww man, that’s sad. Have you started again yet? Was there anything you could use in your restart, like the rock maybe?
