Yeah I wonder if I can send this in to IALPC this year and win something
Its quite annoying because it spreads fairly rapidly, the day before yesterday I cleared it off my rocks, the next day it came back with a vengence.
Last night I did an 80% water change and started using a tooth brush to scrape the stuff off my soil and rocks but only managed to go through about half the valley.
Heck it pearls more than my HC. I should have saved my money on the plants and grown this stuff instead.
