I have been noticing in the past week that there has been alot of this brown algae growing on the sand bed and on the live rock.(see pictures) This brown is sprouting all over the place. I have never used tapwater but I have been using store bought distilled water for top offs and water changes. I have an ecosystem mud filter and current orbit lighting. The tank has been setup for 2 months now. All of my water parameters are great except for phosphates. Any suggestions and how can I remove the algae from the LR.
