I think I have mustard algae!
I was gone for a couple days and came home to no clorine and a brown yellow tint at the bottom and lower sides of my pool. Added 2 lbs of shock ultra blue algicide, brushed, vaccuumed, back flushed filter, repeated. Now it's not sticking to the bottom but the water is cloudy and slightly brownish yellow. I do not have the option of replacing water , due to severe drought and monitored meter from the city. ( they are fining for over use).
Here are my test results from the TF-50
Not sure what to do
Should I add DE to catch the fine particles that seem to be coming back through the filter?
I'm new and have had this pool since may this year.
Thank you for your help
