Your tank is 5-6 months old, this is a common occurrence, if you only have 3 fish & feed every 2-3 days, this bacteria problem will go away on it's own, everyone has given you proper suggestions, it needs nutrients to grow for sure, but it is also one of the oldest life forms in the world, so it is very good at adapting to it's surroundings. If it's any consolation, my tank was 10 times worse than your pics & it went away on it's own after 3 months or so, it gradually covered less area until it was just gone. One thing I know you did not do correctly was use the Chemi Clean per the instructions, because you must treat for 48 hours & then do a water change of 20% before retreating again, you gave up after 1 day, this stuff works, I have used it in the past with great success, but you must follow directions & keep up with it. Good luck & if this little bit of Cyano is making you want to quit, you may want to rethink your strategy.
