This is cyan! Siphon slowly and look for the cause, first do water tests.

Cyanobacteria. When they appeared, I struggled for a long time with various methods. Ceftriaxone 200 mg per 100 liters helped. Apply it at night for 4-5 days, on the first day use half the dose, and after treatment, siphon the substrate.
