I just started getting a green dust-like substance growing on my glass. If you move your hand past it it swirls off the glass. Not wanting to scrape it with a manget so that it swirls around all over the tank... any other ideas of cleaning this out?
I do use dechlorinated/purified tap water for top offs.
My water tests ph 8.2, Am 0, Nitrite 0, Nitrate 0, 76 deg.
Any help? What kind of algae is this?
Thanks!
