I've had a fairly stable aquarium for quite some time and recently a new type of algae has turned up & I am wondering whether it is harmful to the tank.

The algae I'm concerned about is a growing patch in the middle of the tank, which I have zoomed in on in the second picture. It is bright green in colour and I'm not sure how to get rid of it. I'm tempted to just remove the gravel, bleach it and dry it in the sun before re-adding it back to the tank.

Parameters are as follows:
pH: 7.5
NH3: trace
NO2: 0
NO3: 10-15
PO4: 2
