I have alot of micro bubbles or suspended silt or something.
I think its silt of some kind, from looking into the tank it seems to cling to the surface however both of my loc lines blow away from the front of the overflow. so i think they are keeping whatever it is from being sucked down into the sump.
I will update this more in the morning as its late and im too tired to keep looking for a answer.
p.s. Its whats already in the tank thats a problem i dont see any bubbles coming in from the return lines.
