Your cyano is probably thriving on excess nutrients, specifically PO4. Cleanup of the cyano doesn't deplete the source of it growth. I suggest you invest in an accurate test kit to monitor PO4 levels at the PPB level and figure how to control PO4 levels long term. Keep in mind the cyano is consuming the PO4 so its existence is impacting the test measurement results. Good luck.
