Blackout only partially sucessful

[tnnlynch]

Doing a 3 day blackout eliminated all aglae pockets but the green spot. No dust and no bga survived. The spots on the glass are small and isolated but there are several of them and one large plant leaf is lightly dusted with GS. Is GS just tenatious or did I some how allow some light in?

Scrub it off, bump the CO2/PO4 up.

GS can be controlled by maintaining good PO4 levels and good CO2.
Blackout will not kill GS.
