Algae/bacteria over frags

[olaywolay]

in the picture you can see various zoa frags on my rock, although an algae/bacteria has been growing on the rock and even causing the frags to stay closed, will this kill them eventually and how can i prevent this? just want everything open, cheers

I would take every Zoe frag you have and dip them in a Peroxide solution of 80% tank water to 20% peroxide for several mintutes to kill the algae. You also need to find out why your tank has gotten this bad. Check all your parameters for sure.

think its just the ugly stage, its honestly not terrible just growing over the rocks/sandbed

this is is how it looked, this is it now after cleaning sandbed

Algae growing over your Zoes will kill them if not cleaned up. Just something to think about.
