What would you say is the best species of algae for growing in a sump to uptake nitrates and phosphates in your water (aside from Chaeto) I have both grape caulerpa and dragons breath in my refugium and the caulerpa grows super fast but is kind of a hassle to remove. The dragons breath grows a bit slower but I find it easier to remove when I clean. I'm thinking of trying other types of algae in the future, any recommendations?
