Fresh water algae
I bought a piece of pre soaked driftwood at Petco (I know - that should explain it right there, but I really liked it). In the last two days, it has grown some sort of brown/green algae. (See pics).
This is a 10 gallon cold water tank with a Penguin 100, parameters are all within normal range (0, 0, 20, 7.4). I am using an API drop test kit.
How do I get rid of it naturally? Boil the wood? Scrape it off?
