I used a mag-float cleaner everyday to clean the front glass panel. Never had a problem with coraline algae growing on the front panel. I clean the front panel after feeding my fish. I do not touch the back or sides panel, I just like the coraline algae grow.
Obsessive reefer.....Cleaning glass Daily that's a job not a hobby...lol
Yeah it's good until your tank is well established and you have to scrape it off every 2 days like regular algae, then it's a pain....
thats how my tank is!!! its nuts, i love it though!
