I hope you can see where I am going with this.  |
Bob, with out these so called "Evil nutrients" the algae would eventualy wither away to nothing. so it make more sence to find the cause of the excessive algae growth and remove it (yes the nutrients) removing the algae its self is only a bandaid not a cure. and not trying to bore you but Lava rock is a knowen leacher of iron and other minerals wich
are knowen for causeing algae growth
now having said that, it does not mean that every lava rock will leach.. it all depends on the chemical make up of that perticular lava rock.
