i know these are not good shots but if this is cyano then i will be able to be rid of it sooner by finding out who it eats for food.
thanks

Chemi-pure will work wonders.

The problem is too much dissolved organics. Skimming will help. New lightbulbs can sometimes help.

thanks for your help.
i am running a berlin classic on a 90gal with a 35gal sump. i wonder if this is not enough skimming power? it's always pumping out scum so it's working... but is it keeping up? hmmm.
any suggestions will be appreciated.

Decreasing PO4 level is the key for cyno. Reduce feeding and increase flow to the more problematic area will help.

Kalkwasser drip will help preciptate PO4. You can also manually "lift" out sheets of cyno as means of nutrient export.
