OK I've been in this hobby for over 10 years and this one has me baffled. Right now I have a film on the surface of my water and everything that I can think of tells me I shouldn't.
The tank has a footprint of 66"X33" including a coast to coast overflow with two 1.5" drains on durso pipes. The return pump is a Mag18 running wide open.
I swear my water level in the overflow was lower but now the elbows on the durso area about 85% covered with only the tops showing.
I have holes drilled in the top of the dursos and to ensure they weren't too restrictive I even took the tops off, while very noisy it didn't change the height of the water in the overflow.
The ONLY thing that has been changed on this tank is I went from Metal Haldies to AI SOL led's. Is it possible that I just never noticed this film? If so...any ideas on how to fix it?
I feel like this is a rookie issue but it has me stumped.
