How long until water gets clear

[timrf79]

Hoping this is the right section here.
Synopsi’s of the last two weeks:
- All year long pol went from clear to green to clear within two weeks
- Pool Cleaner claimed filter broken
- Checked Filter and replaced Sand
- Replaced gasket in multiport valve, but used pool lube instead of glue to set the gasket
- Fired Pool Company
- Got Test Kit
- Water tested for CYA of 100+, FC of 0
- Drained 2/3 of pool and refill
- Added 2 Gal of 12.5% Bleach
- FC measured at 22, CYA at 60, CC 1
- 4 hours later FC 22, CC 0.5
- 22 hours later FC 15, CC 0
- TA is 130, hence I am doing the dance of lowering PH, letting it go up and then lowering it again
- Opened up Multiport valve, cleaned it, dried it, glued in gasket, put back together, let it sit for 24 hours before running pump
- Over days FC came down to 8
- Adding daily 40oz bleach, end of next day FC is back to 8

I have fine “dust” that eventually settles at the bottom and stairs, you come near it/ step on it it floats away in a big cloud.
When I run my pool cleaner the pool turns cloudy from all the “dust” getting moved around.

Question, that fine dust is that going to filter out eventually, it just takes longer due to the pool size?
Should I run the pool robot daily to help With it?
Should i let it settle and use a manual vacuum on it?
How do I know the valve works right and the vacuum water is not by-passing the filter as before?

That "dust" is dead algae. You need to SLAM your pool until it disappears. One of the 3 criteria for completing a SLAM is clear water, and you do not meet that test yet. It sounds like you're close, so it may only take a couple of days.

It will eventually filter out and running the robot will help to keep it stirred up so that it makes its way to the filter. But you've got to keep it from continuing to grow more first. That's why you can't get rid of it.

Ah…
well the water looked clear once it all settled…

if it is dead algae, why do i need to keep slamming, isn’t the point to kill the organics?
And once dead it just filters out?

is algae like a zombie, coming back from the dead…

 

[jeffchap]

If it's not disappearing then it's getting replenished as fast as it's getting removed or it would be gone by now. So there is still live algae suspended in the water.

Either that, or your filter isn't working properly. I suppose you could drop a bit of stabilizer down the skimmer and see if it immediately comes back out the return. Not too much, just a handful or so.

Which test kit did you get, and can you tell us:
FC
CC
pH
TA
CH
CYA
Salt if applicable

FC 8
CC 0
pH 7.5
TA 130
CH 250 ( currently waiting on the peladow)
CYA 60
tested with Taylor k2006c

Is this a plaster, vinyl or fiberglass pool? Please add that detail to your signature. Thanks

plaster

Your target for 60 CYA is 7-9 so the water is safe as long as it's clear and see the floor in the deep but obviously there's the algae part of the equation which your not doing enough about. Your slam level is 28 if you you want to attack the algae issue.

 

[timrf79]

just to confirm,
With a sand filter it may take a week or more to clear up and the entire time the FC needs to be at 28?
Is there any way to estimate how much chlorine I need for that? About 1 gal per day?

Sorry my mistake but your slam level is 24ppm. For every "1" ppm needed you'll use 29 ounces of 12.5% chlorine. For example if you need to make up 10ppm it would =290 12.5% chlorine.

Run your dolphin and your pump continuously and clean your dolphin regularly. Helped me. First two days the bag had a ball of dead algae.
