What are the dimensions of the tank and the lighting you are using. How long are the lights on each day? Have you identified the algae type? Pictures? Details please.

It's a juwel rio 125 lights are on 8 hours. 2 x t8 that came with tank, bulbs are a marine bulb, a daylight bulb and I have added a arcadia stretch led 60cm 26watt that one. Reflectors on the t8

First thing I'd do is change the "marine bulb" which I'm assuming is actinic, to something more plant friendly like a daylight 6,500k bulb. Algae just loves that actinic lighting. Looks like your algae is black beard algae (BBA). You can treat it by spot-treating with a syringe of 3% hydrogen peroxide. However, the moss wouldn't take too kindly to the peroxide.

Edit:
For the BBA in the moss, you can spot treat with excel (or glut alternative). Maybe reduce photoperiod to 7 hours. Keep up on weekly partial water changes.
