I have an above ground pool (24' round) with a Polaris 65 cleaner.
Pool looks great and water is crystal clear. However, every time I
"unhook" the polaris from the pool wall outlet, there come a great
"brown" cloud. This has been doing this all summer.

I have a sand filter and thought it may be broken internally, but it
is only 1 year old and does filter the pool correctly. I have tried
backwashing for 5 minutes past clear and then rinsing 5 minutes past
clear. It doesn't seem to make a difference. Once backwashing and
rinsing are done, I unhook the polaris and bingo....here comes the
cloud.

I even added DE powder to my sand filter to see if it was just missing
some "algae". No help. Looks like the same amount to me.

It seems that the polaris is somehow creating a stagnant water area in
the top of my filter valving and it doesn't shoot out even though the
polaris seems to be running strong. What would cause the brown cloud
to not come through the polaris. It only comes out when unhooked. It
is just annoying to have a "sparkling" pool and then see a huge cloud
shot into the center of it.

Not sure but are you emptying the basket at the pump?
After vacuuming, leave everything attached, turn off the pump,
empty the basket of the stuff the cleaner picked up then
reattach everything and turn the filter back on.

A brown cloud coming out of the filter is usually a sign
the filter hasn't been back washed. Shouldn't really
happen with a clean pool.

I stopped using the pool cleaner years ago, more trouble than
its worth.



Yes. Everything is cleaned at one time. Something really weird must
be going on. First I use polaris, then clean baskets, back wash,
rinse until clear. Then decide to unhook polaris and this huge cloud
comes out. Its like this stuff is so small that even the DE powder
doesn't catch it. But for some reason doesn't leave when backwashing
and rinsing....... Also the cloud won't come UNTIL the polaris is
unhooked. It must be some kind of pressure problem that isn't
allowing the dirt/algae to come out until it is unhooked. Could the
sand filter somehow be "tunnelled"?? Would this cause something?
