I've recently started getting long strands of brown cyano on my leathers in the high flow area and a little on the sand bed.
My understanding is cyano will appear when certain conditions are met - primarily a high level of nutrients and light.
I've got a 15g AIO, filter floss and some seachem matrix but otherwise its just live rock doing the filtering.
26 degree C
pH: 8.1
NH3: nil
NO2: nil
NO3: nil
dKh: 8.5
Phos - don't have a tester
Was worried with my nitrates sitting at negligible levels dinos could be a concern but don't understand why the cyano's appearing?
Light schedule was recently changed with a slight reduction in hrs, white light's there but lower than it was.
I don't have an RODI unit, use store bought water in my inverted bottle ATO. Does say it's created via RO though.
I feed 4 times a week, roughly a quarter frozen cube for a clown and dottyback - not much going to waste.
Only messy thing i can think of is there is a bit of red gunk that builds up in the filter chamber that i periodically clean out.
Any thoughts as to what's keeping the cyano happy?
Cheers
