Hi there i have recently put some live rock into my new orca 550. Its been running for about a week and i have added 1.5kg of live rock.
All levels are as they should be but there is some white 'cobweb' like growth on the live rock which appears to have grown over the last couple of days.
It looks soft as it is moving in the water flow but its spreading and has occured in several different place on the small amount of LR

Any advice on what it maybe folks???

Thanks
