So I have a 12 gallon starting to turn into a reef it's going on three months and I'm starting to get green algae on my rocks mainly only where the light is shinning the most also get brown/green on the glass that pops up a good amount weekly. I do weekly water changes and readings are fine don't over light the tank or over feed, I'm also using tap water and dosing but will be getting an DO/DI unit within a week I'm also upped my salt mix and got red sea coral pro. Do you think when I start using the rodi unit the problem will get better? I also have small signs of purple corralline algae so I have to be doing something right......right? Any advice would be awesome
