black turf

[new2scrub]

ok so after noticing some cyano and dinos in my display last week I replaced all my CFL bulbs with shinny new ones,,but I am noticing that the dark "turf" algae is still out-growing the nice green algae in my scrubber. I used a hacksaw blade in a holder and removed 95% of the turf on the last 2 cleanings but it grows so much faster than the green algae. any tips? This is not a complaint as my scrubber is still doing it's job nicely,,I just strive for perfection:)

As nutrients come down, more green will grow.

when this scrubber was about 2 months old I had a ton of green but now it is getting replaced by the turf? is this a normal cycle?

I will be sending my water out to be tested soon and will post the results

Yes but you need to scrape off the turf... is does not filter as good as gha. See the end of this vid...
