If the pool has a DE (diatomaceous earth) filter, chances are one
or more of the filter grids has a hole and needs to be replaced.
Even a small hole in one of the grids will be enough to cause
If you have a cardrige filter/filters there can be a whole. Has allot of
stuff been blowing in the pool ? Have you recently cleaned the filters? Have
you had the water tested? How often do you shock the pool? How long do you
run your filters and how many gallons is your pool? I notice in my pool
after I clean the cartridge filter the pool takes a few weeks to get really
clean. I was cleaning the filter to often, they seem to need a little
debris on them to catch the small partials. But I would not use the word
Milky white to describe the water. It did get a little cloudy after using
Home Depot shock but not even for a day. I've only had my pool about a year
I have the water checked every three to four weeks and don't want to omit
how often I check it. I thought when we got a pool and sold the boat it
would be less work and $$$, Now I have a 22,000 gallon step down boat. Good
luck post what you find out.
I have cardridge filters. I recently changed the filters after about 10
days. I guess I should change them more often now.
I test the chemicals almost everyday, the chemicals are all fine. I
don't usually shock the pool. How often should I shock it?
I run filters 24/7. I should mention it is not house pool but a pool on
a property I own. It's an in-door pool.
Thanks for all your replies, as I understand this, it is most likely
the filters that are causing this.
Wait not so fast. There is one other option to check as well. Has the
pool been repainted in the past few years? If so, it can be the paint
chalking off. One test is rub your hand below waterline and see if
there is any white residue coming off on to your hand. This is one
scenario I had at a previous home. Lessoned learned - never paint a
Those Cartridge filters last years you just clean them. Buy powder shock. Go
to a pool supply, They will point you in the right direction. Bring water
sample and measurement off pool ( Close) so the can tell you the gallons if
you don't know, Running filters 24/7 WOW I would rethink that $$$$$$$$$
Shock it, you said you havent been doing it at all so it sounds to me like
your in desperate need of a good chlorine shock treatment.
also, by your post, i see your in need of some pool training, go to your
local pool supply shop and talk to them, bring in a sample of water ( a
couple of cups will do it) and they will test it for free for you.
One final thing, i knew a guy who used to stand there and drip his test
chemicals directly in the pool and watch the reaction - he claimed he
"could tell" what condition it was in that way - NOT ! When i tested
his pool it was way way off - took me 2 weeks to get it back in balance.
Once a pool is brought into proper chemical balance it will tend to stay
there with very little work and a minimum of chemicals **IF** you stay on
schedule, maintain the filter properly on schedule etc and do it right. A
balanced pool thats neglected for too long will stay ok for awhile and then
suddenly go south and it will be a real bitch to get it back in shape
