But my aquarium have good water movement i think. Mi filter is 500 GPH.
The food is Hikari Discus bio-gold. The food can cause the algae? I have 1 corydora for clean. the only posibility of cyano that I think is water temp, old spiral bulbs, food and pphosphate. I need to fert potassium? I think that high phosphate in water and low potassium can lead to algae???
