Adding Polyquat, How To?

If you have a submersible pump, usually used to remove rainwater from the cover, you could drop it in without a hose connected just to stir the water. Be careful not to let the cord end get in the water.

Worse comes to worse and you can't figure a decent mechanical way, mix it out with water in large buckets and add to pool in quadrants, then use your leaf net or brush to "stir" and mix it throughout - move to the next quadrant and repeat until the recommended dose is in.

Run your pump on high, then turn it off. The water will continue to swirl for several minutes. Add the Polyquat then. Of course, this is the last time you will use the pump for the Winter. Your next step is to remove the pump from use for the Winter.

I simply add about a quart of Polyquat and wait 24-48 hours. Usually, I just run the filter, this year I left it on recirc for that time.

Polyquat WILL be filtered out by media if it's not adequately diluted--don't add it to your skimmer. It's thick and oily.

Now here's an IMPORTANT warning: If you add a lot of Polyquat (I added a quart yesterday), then 24 hours later your FC will be low or NON-EXISTENT! This is normal--do not worry, if you don't have an algae bloom you won't get one, as long as you don't leave it. Merely add chlorine until your FC is where it belongs. My FC went from 4 to 0 in 24 hours.

But it doesn't worry me because I expect it and add chlorine to get it back where it should be.

I have a two speed pump that I run on low most of the time. If I backflush the DE filter in preparation for winter closing. Can I run the filter on low speed without damaging it so as to circulate the water and mix in the Poly quat without the material being caught by the DE since it would all be gone after the backflush?
