What's this in my res & is it going to be a problem?

Put my soundcard back in yesterday after fixing it (managed to snap the end part of one of the cables off inside the port. Clever, I know) & noticed this funky looking stuff at te top of my res.

After the pc had been off for 20 minutes it seemed to have cleared up a bit making me hopeful that it was just some form of foamy bubbles but it also looked like the level of fluid had gone down slightly. This is my first watercoooled build so I'm not really sure what's going on here...

Here's a pic:

It's normally that colour so that's no issue. It looks clear usually but any kind of light on it ie the camera flash makes it look like blood. It's one of the Mayhems pre mixed fluids.

The top tube is a return line & it is a clear acrylic tube inside it rather than a column of water.

Do you think it's something I should just keep an eye on or is it likely to be something I should deal with now because it could cause problems down the line?

Thanks.

Filled it through the top of the res before I did it up. Was a bit of a fiddle but I wanted to keep it looking neat.

I'll just keep an eye on it then & see what happens. TBH I was unhappy with the colour of the fluid & am considering changing it out to a pastel so (if I get round to it) I'll check it all out then.

Thanks.
