What is this on the surface of my tank water?

  • We are currently upgrading MFK. thanks! -neo
OR getting a EHEIM skimmer 350 and problem solve, your water surface will sparkle clear with surface skimmer.
 
turn off or move the returns/spray bar, then get paper towels and place them
on the entire surface gently and let it soak for a few seconds and repeat as
much as you need to completely get rid of the protein film. quick and easy fix.
as for the long run feed less and get a skimmer i guess lol..
