Hi everyone! So, our pool was recently drained and refilled due to some plaster (pebblesheen) repairs 3 days ago. It is finally full and now I notice the “shredded tissue” . I am perplexed.

1. Is this white mold, biofilm, something else?
2. How did this happen being that it is fresh water that was filled only 3 days ago?
3. Could it be due to my filter and/or pump not operating properly or perhaps dirty? The filter was last cleaned last summer.
4. How can I fix this?

Thank you in advance!

What are your FC and CYA levels?

What test kit do you have?
