HELP !!Have skimmer scum algae bacteria Don't know!!!!

[bullseye7007]

Had some algae problems because of my lack of maintaince. Shocked pool added algacide. water is clear and clean with no signs of algae in pool.

Problem is I have 2 skimmers and they have some type of a algae scum that forms inside of them along the water line. I can wipe it out and regrows fast!. I have shut pool filter system down at night and filled with some shock also wiped out with algacide and NOT taking care of it. I clean them out regularly each day some times 2 and 3 times a day . Shallow end gets more build up than deep end. Appears in color blue green and grows quickly reappearing within a short time after being wiped away. I have noticed that a beetle floating in skimmer it is growing it on the outside of the beetle body TOO YUCK! Is it a bacteria? I need help and appreciate any suggestions. I have a sand filter 30,000 gallons. Water temp like 84 degrees. 20x40 inground. Thanks

Post your test results, but it sounds like you still need to elevate your chlorine level.

I was thinking it might be a residual foam/scum from the algaecide since it's only in the skimmers...

Thank you for your replys. I appreciate the fact there are those out there willing to help.
I took the pool water to a local pool store and they tested water said chlorine is a little high ( due to shocking)ph and alakinty just right should not be changed. They suggested that I try natural clear chemical, possible residue from sunscreen collecting service dirt and gathering in skimmer and collecting to skimmer walls althougth I have never had this happen before especially growing algae like substance.
I dumped the amount recommended Natural Clear in so we will se what happens.
I hope if this works... so it will help some one out there with the same problem and they will be able to diagnosis it more quickly.
Thanks, bullseye
