White film on pool surface

[poolnoob626]

Opened a pool that hadn't been open in 2 years, ph test showed yellow on my taylor 2006 test kit. It is a vinyl liner pool 18x35 around 25k gallons.
There is a white cloudy like film on top of the water, to my understanding I have sort of balanced the water, the ph is at 7.2, free chlorine 4, alkalinity 110. Yhe pump is starting to get like a green tint inside as well as the basket. When I first opened the pool and was vacuuming all the dirt it had backwashing would show dirty black water, the pool is now clean but when I backwash sometimes the water comes out green ish which is odd because the pool is clean and free of algae. I have attached a picture of the skimmer where the white film like thing kinda mixes into this blue ish green ish gunk

Copper?

Open up the filter and see what the media looks like. DE or Cartridge is easier to see the copper buildup.

It is a sand filter, I believe there is also sand being sent back into the pool, I will try that though thank you

More than likely you have an algae bloom. Cloudy white water is a distinct sign of algae. Water doesn’t have to be green or have floating mats of algae to be considered full of algae. In fact, you can have crystal clear water, measurable FC and still have algae in the water.

You need good test results from a reliable test kit, not one that is old. Update your test kit supplies with fresh reagents and prepare to SLAM the pool. In the mean time, while you’re waiting for a fresh test kit, fix and deep clean your filter (it sounds like there’s a bad seal somewhere letting dirty water back into the pool) and start stocking up on liquid chlorine.
