Others already said to please add photos of the algae under neutral light but I'm noticing you are using Elimi-NP and ReefEnergy which means you are carbon dosing, adding amino acids, fatty acids, and vitamins. This in itself isn't an issue but it can boost growth of bacteria and protists extremely so maybe the "algae" isn't actual algae but bacteria or for example dinoflagellates due to excessively feeding them.
Of course it's better to let the community see the issue first before jumping to conclusions but that's something you might want to keep in mind.
