In my 300L 'south american' setup i have had nothing but troubles with algae.
Have had greenspot,brown algae, hair algae.
Currently have Brown algae, Beard algae, and string algae.
And to be honest i have just had enough of it.
What could be causing it?
Im seriously considering putting all the fish and un-algaed plants in a large plastic container and starting over.
But what i need to know is if all the algae could be transfered in the filter(im buying new hoses and filter intake/output.
