I've had this strange calcium like macro algae recently return, it was nearly gone and I can't say what changed to allow it return in force. The only change I can recall is that I did a decent water change and it seems significantly worse since then. I rarely do any water change. What eats this stuff? My phosphates and nitrates are zero and I only feed one cube daily of Hikari spirulina brine shrimp or Mega-Marine Algae, nothing else, no other added nutrients. I dose only B-Ionic #1 and #2 and Red Sea NO3Po4X and have not changed either recently. I grow plenty of macro algae in my refugium and run a Tunze 9415 Skimmer on my CADE 1500
Does anything eat this stuff? Can anyone recommend how I can better control it naturally?
