Errrthing, yer doin' ERRRRTHANG wrong!
As opposed to "fixing" algae, I say you take preventative measures instead!
Why pour in bottles of goop or spend $$$ on Amanos?
- Amanos only munch on the tips of algae, and only when there is no other food available in the tank
- Photoperiod too long (IE too much light)
- Unbalanced nutrients (not enough plants?) algae pops up to consume excess nutrients in the watah so get nitrite hogging plants like mosses, water lettuce, duckweed, water sprite, etc
