Disappearing cyano algae

[meiyouwenti]

I have had a problem with a red cyano algae appearing on the substrate of my tank every afternoon and evening...overnight it completely disappears! I haven't been able to figure out what is going on but I used a Chemiclean Red Slime remover..and it seems to have worked in the past two days. I guess this means that it really was a blue green algae (cyano)...anyway I recently read that "(the amphipods,clopepods and isopods as well as a range of worms, among other creatures)...make a major contribution to algae control in the reef aquarium particularly in keeping down cyanobacterial growth. They are most active at night and are the reason that in many tanks with cyanobacteria problems, the cyanobacterial mats seem almost to disappear overnight but grow back during the day."..SO MY QUESTION now is: Does this mean that if I cut down even further on my feeding that I still have a large food supply of amphipods,clopepods and isopods that my fish are able to feed (or are feeding )on?
Thanks
