Are you running C02? If not. Flourish excel will help as well. I had similar struggles with algae I reduced feeding, reduced lighting and added weekly doses of excel after water changes. Made a big difference
No co2.
I add daily 27 ml of karbo. It's called happy life karbo.
Good for plants and algae prevention, supposedly.
I've never heard of flourish excel, care to enlighten me?
