Yellow water help!

[PeaP]

Hi.
I dont know why but my water is yellow and murky.
It was also yesterday so i made a waterchange add aquasana and tannin extract like always, but my water wasnt going brown but yellow.
My water parameters are like always and fine.
I added prodac substrate but that was 2 weeks ago.
I also have a lot of biofilm on surface so tommorow i am getting my new skimmer.
Please help me. The first photo was taken one week ago.

Looks like the problem might be a
bacterial bloom or an algae bloom.
Either way, regular weekly WC's should eventually take care of the problem.

Not usually. Both varieties of bloom are common in newer set ups.

Thank you.
I will make a waterchange and run skimmer and carbon.
I hope that it will work
