Reusing algae covered rock

[chromakey]

Good Day:

I removed an algae covered rock and it is soaking in fresh water outside for about two weeks. When I pulled the rock out I used a electric power washer but the red algae didn't come off easily.

Before I "cook" the rock what would you recommend to remove the algae from the rock?

Thanks,

Michael

ive used peroxide on algae rocks and it works wonders, just the 3% stuff you get from the store, i used a mix of tank water and peroxide and let a rock with zoas on it soak in it for like 3 min, took like 2 days and all the algea was gone and all the zoa were fine and opened,

i would use a mix of peroxide and water and dip and let the rocks sit in there it will kill any living things and end the algae problem

+1 to the above, H2O2 works great at removing algae.

Hi:

The rock is already dead. I guess I can use hydrogen peroxide to help remove the algae before I cook the rock.

Thanks,

Soak the rocks in a bucket of water with a few cups of bleach , it wont fully dissolve but it will turn transparent and be DEAD for sure .
