phosphours reduction

[swhastan]

My 10G tank has 0.5ppm of phosphorus now.
What's the best way to reduce it?
Also, what can be possible reason of this level of phosphorus? Overfeeding? - I'm using RO water. In case of 60G tank, there is undetectable level of phosphorus now.

anyone?

I prefer growing and harvesting macroalgae, but there are other methods as well, such as an iron-based phosphate binder.
