Newbie questions

[asylumdown]

Is there only one aiptasia? If so, do yourself a giant favour and remove the entire rock it's on. Then blow torch the hell out of the aiptasia in it's hiding hole until there is literally nothing moist left where it was attached.

Once the aiptasia starts to spread to other rocks (and it will do so VERY quickly) your options for eradicating them completely dwindle rapidly.
