Not sure what the red one is, may be a type of bacteria rather than algae. Looks like you've got some serious algae issues there, I'd be cutting your photoperiod down to 6 hours for a while or halving your intensity [emoji106]
There was an algae spike after I upgraded my lights to the finnex 24/7 SE. I'm using the 24/7 mode. I also don't feed a lot.
