Cyano is a wonder of nature and is one of the most efficient nutrient scavengers on the planet. It's difficult to troubleshoot because of this. It will grow with or without nitrate in the presence of phosphates. Some corals have a symbiotic relationship with cyano which fixates nitrogen. Getting your phosphates as low as possible will help other microorganisms out compete the cyano. Educated guess that you have high organics in the presence of phosphates and light. Ultralife Blue Green Slime remover available on Amazon will get rid of all visible signs of it but it will eventually come back if you don't fix the root cause. Just follow the directions - do one treatment and be patient. In about a week there will be no sign of cyano and it won't measureably affect your biofilter. I suspect Chemipure is a similar product based on what I've read but I've never used it.

Thanks again for all the advice.
It looks like the phosphate test kits are not available locally so I will be ordering online. I'll update after I am able to access the phosphate levels.

Good afternoon everyone,
Last week I clean everything in the aquarium: rocks, glass, etc and performed a 50% water change.
I also decreased the light to 7 hours although there is some ambient light that would also reach the aquarium during the day.
Feeding was decreased from twice a day to once a day.
The water column looks clear.
The phosphate test kit came in and I perform all the test including the phosphate test. Please let me know if there is anything that I need to look into changing or optimize at this point.

Have you tested your tap water for phosphates, what does that read..?

Water at the tap was 0-0.25 ppm. It was difficult for me to tell the difference on the test card between 0 and 0.25 ppm.

Target is phosphate = zero. Clean substrate, clean filter media, feed less.
Do you feed flake food? Switch to pellets.
Do you use buffers? Avoid this if you can.
