Hopefully this is the best off place to be posting this. First time
poster- just got assigned to my parents' pool (6 ft. under ground
pool). moslty just needed a good skimming and brushdown- well
enough... i needed the exercise and tan :) Also noticed a bit of algae
growing on the corners and near the skimmer intake. Gave it a good
scrub and gave me the decision to shock it with this stuff in their
But the water is still a real murky color. At first it was more green,
but after getting rid of all the debris, clearing filters and throwing
in a quick bag of SHOCK... the murk seems to be turning more a blue
color. How would I got about making it crystal clear? We have lots of
chemicals in the garage, pH decreaser, shock, algae killer, some other
assorted. What will be the next step?
Thanks for any thoughts all.
I have my doubt that the chlorination system works right. The pool
does not look chlorinated and it's on five with only half of the top
intake thing. I have my doubts about the pools intake pressure all
Find a pool supply and take a water sample in and have it tested. They will
point you in the right direction. Even with a home test kit it's hard to do
the entire test. If you shocked the pool your chlorine will most likely look
right. I guess they gave you no instructions
Keep testing the water once a week and add chemicals as needed. Don't
expect overnight changes. Adding Shock will cause other fluctuations
to happen. Keep filters clean. Read and follow all directions.
(You asked for any)
1. Drain the pool.
2. Clean the filter. (You failed to include the important part about if it
is a sand, DE, or cartridge filter.)
3. Hose down and scrub the pool surface, acid washing if necessary, if only
4. Refill pool with new water.
5. Replace or clean contents of filter. Make sure inside of filter is up
to snuff. If it's a cartridge, you can clean it. If it's DE, remove the
DE, and make sure all your screens and assembly are okay.
6. Invest in a cyanuric acid test kit. Cyanuric acid is the stabilizer
that is added to chlorine to keep it from evaporating and going into the
atmosphere. You will need to buy a bottle of stabilizer with the new water.
Once your cyanuric acid level is right, you will use LOTS AND LOTS less
chlorine, and you only have to check it like once a year unless you drain
and refill the pool.
7. From there, get a good test kit, and don't really spend a lot on phUP
and phDOWN chemicals because if you got it right, you won't have big ph
You asked for any opinions. Mine are to start with clean water, put the
right chemicals in there, and start correctly from square one. Who knows
what happened in that pool in the past. You think you're going to clean out
all that gook and end up with clean clear water?
I don't think so, Tim.
START with clean clear water.
I was just curious if I would get a reply. As you say draining the pool
is a last resort the deep end of my friends lifted one foot. ( ground water)
I would thing twice about taking advice from someone saying drain the pool,
they don't know what there talking about.
It sounds like you killed the algae but left debris that is finer than
your filter. This debris is left to circulate and cloud the water.
If so you need a "Clarifier". Just add the clarifier to the water and
it will make the fine particles coagulate so that your filter can
remove them and produce crystal clear water.
I've been fighting green algae as well. I understand that I have to
shock it and put in algaecide (which I did). I know you're supposed
to brush and backwash pretty often. After you backwash, do you need
to replace the DE every time? Just wondering as that's using a lot of
Make it uncomfortable for algae before you make it comfortable for
Drop the pH to about 7.0 and add about 20-25 ppm chlorine (read the
dosing instructions on the label). It will clear up. Keep filtering.
When it's clear, balance the water.
