the liverocks were bought a week ago
saw small amount of short green and red hair alage grown on them 2 days ago
could have left the container in the balcony and forgot the sunlight may reach it.
the rock smells ok since day1 and now is even better so only did air-ing and water change every 3days so far, while waiting for the tank.
now continue to air it, water change and coverup to minimize stray light
what else can I do to kill off the alage?
thanks
