I have an AG 16' pool that I'm trying to figure out why I can't get
the water clear. It's 4' deep and I can not see past 1/2 way down, the
water is white-ish. Also, I noticed there are tiny bubbles on the
sides of the pool, almost like carbonation in my beer. These bubbles
don't seem to actively bubble to the surface. But if I brush off the
bubbles, they seem to be back the next day. But I never remember
seeing bubbles on the sides of anyone else's pool.

I have a Hayward sand filter on it with a 1hp pump, more than enough
flow for a 5000 gal pool..

I've had my water tested at the local shop, most everything looked
good. I asked about the milky water, no luck.

This all started 3 weeks ago, I left for 3 days, with the pool cover
on. My crystal clear water turned green. At that time I only had a
pleated cartridge filter. I shocked, changed filters and attacked as
best as I could. I got the Hayward 2nd hand, and that seemed to help
with removing the remains of the algae after my shock treatments. But
my water is milky. I may have overused a clarifying agent, I think I
used it 2 - 3 times in one week, I was then told only once a week..
Could this be a contributing factor???

Any info on milky-white water with sidewall bubbles??

Thanks in advance..
Mike

I googled "swimming pool, milky water" without quotes and got some hits
that might help. Try it.

Sounds like dead, bleached algae. Needs more chlorine and filtering to
break down and filter out. Get pH down to 7.0 and avoid cyanurates when
you get the chlorine up.

How long are you running the pump/filter?

I was running the filter 24/7, figuring it would finally get out the
suspended items, no luck. I would backwash every morning until the
sight glass would run clear. I then started to run the pump for only 8
- 10 hrs. When the pump was off overnight, I brushed the sides to
remove the bubbles thinking that somehow the pumpaction was causing
the bubbles, there were bubbles on the walls the next morning. The
sand is new in the filter.

5 days ago I added a clarifier, I was told this was a once a week
treatment. Reading the product label warns that overuse can cause the
opposite effect. I figure that if I overused this 2 weeks ago, by
backing off it would hopefully resolve the problem, no luck..

I bought a DPD free chlorine test, in addition to my OTO. The OTO
shows about 3.0 ( I liquid shocked yesterday), the DPD shows between
1.5 & 3.0.. One item of confusion on my part, I thought the DPD test
was a 2 pill test. The one I have is a 1 pill test. The pill supply
packets have DPD No. 1 printed on it. Am I able to use my OTO to show
total chlorine and the single pill DPD for the free chlorine? The pH
shows about 7.6..

One previous response was:

Do I need to drop my pH and raise my chlorine to work this out???

The guys at this forum have helped me in understanding pool chemistry ands
solving problems more than any other place I have found...
