i just found my old thread that i started a couple months ago asking a question about this topic. as i remember, i had just discovered that one of my types of algae would form a mat when floating and i was looking for more information on the use of algae for aquascaping. after getting a bit frustrated with the lack of information about the topic on the internet, i just decided to invent my own methods.
anyway, i will continue this topic over in the aquascaping forum in the thread titled "aquascaping with algae".
