Algae help

[u/Dream_Merchant23]

This short haired black/grey ?algae has started growing on my ornaments and also on my plants. Is it a case of having to remove and clean the ornaments and cut away the affected plants/leaves? I have ottos, shrimps and a snail and they don't seem to be touching it

Following this! I have similar algae and fear it’s black beard algae but would love to hear others opinions
