I just started my Red Sea Reefer 300XL one month ago today. I just started to notice algae starting to breakout on sand bottom in a few areas. Cutting back feeding, increased water flow slightly and cut back lighting cycle by 1 hr for 11hrs of lighting using 2 Red Sea LED90’s, preformed 50% water change 2 days ago and 25% change yesterday. I’m trying to do research on Dino’s vs Dinoflagellates to attempt to identify. Wanted to see if you could help. Before water changes color was reddish brown this am color is light tan and water flow increase is lifting algae off the sand a little at a time. Would love some advice so I can stay ahead of this or what to watch for from here? I am Using a new RODI system testing 0 on output side. Thanks for your time in advance. I’ve been out of trade for past 10yrs but used to feel I had all this knowledge I’m struggling to recall at my older age lol thanks.
