What is this crappy looking stuff?

Parameters= ca440-alk8.4-mag1400-No2=.0-No3-.0 and ammonia .0-PH=8.2-Temp=78
There is good flow to the affected areas. Could this be caused from the 2part being blown into this area. When I dose I do so by adding it directly into the high flow area of my PH, which then blows across the tank? It seems to get worse throughout day lights.

 

Looks like cyano to me. Are you using GFO?

 

Agreed cyano, siphon it out whenever you see and with your sand the sand too.

NO3 and PO4 will be 0 on tests because cyano pulls it out very quickly.

 

Yup just started ClearFX Pro last Friday. And in the last week I've changed out 11g's of water. Which is about 50% TWV.
Feeding Dilly all this frozen

Dang it! This isn't good.

 

I would boost the WC schedule and volume since you are feeding so often.

 

Well on Tuesday I vacuumed it all out~including the substrate. Put a major dent in it Almost totally gone. Rearranged the ClearFx Pro in my lil canister filter today for better flow, hopefully this too will help.
I am now rinsing off all frozen foods with ro/di water, double time

 

Moved to Algae.
