Why do I keep growing this B.s. Purple algae!!

[SammyWoodywoo]

I keep getting this purple algae stuff on my sand bed i cleaned all the algae out but eventually it came back. I cleaned out the whole sand in the tank and put new sand but it came back after a month just cleaned out pretty much all the purple algae today but how can i avoid it coming back this time? I also noticed small purple circle spots On the very bottom of tank and on very low sides of the glass tank

Increase flow, increase water changes, decrease feedings, manual removal and wait it out. Do that and you can beat it...

My question is simply how do I get rid of the cyanobacteria algae
