Thoughts / tips on getting rid of Cyano? My sand bed is getting quite covered in it. I have been running my lights from 2:00 PM to 9:30 PM with a sunrise / sunset timer that works with my stock lighting. I just reduced my light time by an hour (starting at 3:00 PM) I feel that my flow is good, this just started happening two weeks ago when I started to direct feed all of my corals a cocktail of reef roids and live phytoplankton.
I have started to do this with the coral feeding, I feed once a week on the same day I do my weekly water change. I feed the coral and then a few hours later I do the water change. My logic here is to keep the nutrients down.
My guess is with the nano tank even small amount of nutrient introduction is a heavy load.
I have not done any sandbed vacuuming as part of my water changes, perhaps I should start there?
