I live in central texas. We got hammered with rain for about 35 days. My pool turned into a green algae swamp because of it. I finally got it all clean, and water is almost crystal clear now finally after almost 2 weeks of dealing with it.
I noticed the pressure coming out of the jets had gotten really really weak. After some researching, I backwashed the pool for about 15 minutes and cleaned out the pump basket. Looks like that took care of that problem. jets pressure is strong again.
However, the Polaris which worked great before all the algae is still really weak. It barely pushes along now. The stream that comes out the back end of it to push it along is not strong enough to make it roll. I hoped cleaning out the pump basket would fix it. but it didn't..
my pool is almost 100% clean, if the polaris worked like it used to, Im sure it would clean all the last bits of crud in the pool...
