Thank you pool doc!! Your the best.....

Congrat's, it's great to see your clear blue water. Perhaps as you lurk, you can offer your experience to others who have unfilterable cloudines. Have a great season!

Congrats on your clear water! Mine still isn't clear all the way. I have a whole new filter on the way and may try adding clarifier if the new system doesn't clear it up.

Just to revive this thread to give aditional feedback.

2011 and 2012 I had cloudy pools that did not clear. I re read this whole post. What I can say is I did not use polyquat upon closing those two year. Is it related? IDK.

All I know is the past 3 pool closings I use polyquat. Upon opening, even with just my leaf cover, the pool stays somewhat clear. Just a fine layer of green on the bottom maybe. Pool cleared up fine the past couple of year with in days..

Not sure if it was that leslies algae stuff I added those two years.. Whatever it was it wasn't polyquat I know that for sure...

Well hope all is well here . I am sorry I have not been around.. Ill try to pop in more often.

Hi. Good to hear from you.

You have a long history. I use polyquat too, but only on closing. After I use it, I bring my FC back up to shock level.

Don't be a stranger!

The polyquat certainly helps and it's been part of my closing routine for many years. But if you shock the pool thoroughly before you close, and open before the first algae bloom hits, you should be fine.

Meanwhile you CAN use a little polyquat weekly to inhibit algae, just 1 to 1.5 ounces. Polyquat can keep algae from starting if your FC goes too low briefly.
