Hey reefers. I recently have been every busy with work. And missed a water change and now I have horrible cyano. I would just like to know what you would to to treat it. I have 20 gal reef been up for 8 months now. Pics are a week old it's much worse now all over pumps and glass

Right now your best solution is to use your sand vac. Vac out as much as you can and replace missing water with fresh salt water. Do this for a few days. You can also try a black out ( no lights for a day after the vac job). 1 day without light will not hurt your corals or fish. If you need to wipe the pumps, use paper towels. The cyano will stick to them.

Make sure it's really cyano. Suction a hunk of the mat and put it in about 2 cups of tank water, then add 1-2 cc of H2O2. Come back in 5-6 hours. If the water turns pink and the mat green it's cyano. If it's not affected it's probably spirulina and should respond to Chemiclean.
