[Jaws]

I fixed the skimmer so it's not throwing out bubbles anymore but what's the best method to counteract the cyano now that its forming on the bottom. Eventhough there are no bubbles coming out of the skimmer anymore either, there are still tons of bubbles constantly forming on the rocks and on some of the corals.

parameters:

Calcium 430
Alkalinity 9.2
Nitrate (according to those inaccurate Hagen kits) around 10 mg/L
Ammonia 0
pH 8.3

Any suggestions?
