Algea Blowing Out Jet

[godstreasures1]

I have a mild case of algea in my pool. I have been brushing the walls and vacuuming the floor daily. When I am through vacuuming I always backwash and rinse. Today I noticed that when I turn it back to filter algea blows out my jet. Can anyone tell me how to stop this?

Hi, algea will blow right through a sand filter. You must kill the algea first. The pool chemistry experts have given some great advice in this forum for getting rid of algea. Look around a bit or maybe one will post here with directions.

Best of luck, Dennis

I wonder if your valve has a 'Rinse' position and if you have a sand filter? Typically after backwashing, you go to rinse for only 10 seconds or so to blow anything out the waste instead of into the pool. Rinse puts the filter in the normal filter flow mode but directs the output to waste. To catch really fine stuff with a sand filter you may want to consider adding a little DE powder.

Have you shocked your pool to kill the algae first? If not, then you're wasting an awful lot of time and water by vacuuming and brushing--depending on your CYA level, get your pool up to shock level and keep it there until the algae is dead. That, along with the other stuff you're already doing, should take care of the bloom!
