cloudy water

Postby key » Sat 19 Jul, 2008 08:34

hello all...this is my third pool in 4 yrs and i have never had such a problem. first my pool(abouve ground 18x4) was great for about a month then it stormed(go figure)! i got algae and put some 50% algecide in the pool. It killed the algae but it left my water extremely cloudy. Its been almost 3weeks and I have used sink and sweep which did gather most of the particles to the bottom and my husband got in the pool and manually vacumed the bottom with the vacum hose without the attachment. this has cleared up a great deal but it is still cloudy. you can actually see the white particle floating. I did have a problem with the ph but that is fine now the chlorine is good. One day the pool with be beautifuly clear and have a huge gathering at the bottom of dead algae but once i vacum it up the clods persist. I have used clarifier, shock(which stained the bottom) and its still cloudy...the pool store isnt going to be much help cause all the levels are within range...what the heck to i do????? my kids are dying to swim and i dont know about you all but spending 350 for this pool then another couple hundred in trying to clear it up is mind boggling and pocket draining. i thought about draining it and starting over but the particles will probably remain. HELP

swimming in cloudy/shocked pool

Postby starsplitter » Sun 20 Jul, 2008 15:50

I am trying to clear my pool as well. It is finally blue, but cloudy. We are shocking it a lot, which seems to be doing the trick. Can we swim in this water or is there a time frame we should wait?

Thanks,

Coming in late, but what a timely subject. I have all but lost faith in my local pool store 'experts'.

When I opened my pool June14th, it was nasty green, but after shocking it (1/3 times more than a normal weekly shock), it cleared up and was perfect. Fast forward to the week of July 18th. Started getting just the slighest hint of cloudiness and a tinge of green. Went to pool store with sample - no chlorine registering. After buying $82.00 dollars worth of balance, stabilizer, shock, algecide, and a chlorine 'stick' to put in the skimmer, my pool became a murky green mess. Soooo, back to pool store with a sample. Still had low chrorine. Told to scrub sides (which I already do on a regular basis), buy clarifier (to the tune of $15.00 a bottle) and shock again. The pool turned blue but was totally cloudy. Back to pool store with another sample. Told no chlorine and to use a flocculant ($20.00). Applied, recirculated all day and left pump off overnight so stuff would settle. The pool cleared up somewhat and I vacuumed to waste. Still not as clear as iI like it or has been in the past. Back to pool store with sample and told "no chlorine" and I must have "mustard algae" which "eats" chlorine. Okaaay. Bought heavy duty algecide (some sort of stuff with copper) and heavy duty (i.e. more expensive) shock. That seemed to do the trick, but 36 hours later I tested the water and it STILL registers no chlorine. So, I shocked again. Looks good now, but at the rate I'm going through the more expensive shock, I'm about ready to have the darn thing demolished and put in a jacuzzi! I have better things to do with my time AND money.

Um, sorry for the vent, but I feel the OP's pain.

If you want to cut down on all these costs the best thing you can do is get a good test kit so you'll know what's going on in your pool.

Much of what a pool store sells you isn't needed or wanted for your pool. Unless you know your cyanuric acid level you can't accurately shock your pool. Without a good test kit you can't know what your cyanuric acid level is or what your free chlorine level is when you shock.

From the chemicals you listed adding, some will add other things to your pool that you may not want. The chlorine stick is probably trichlor which adds cyanuric acid and lowers pH. The shock you added will add either cyanuric acid or calcium.

High cyanuric acid levels make keeping algae away difficult. Low CYA levels and your chlorine is lost to sunlight very quickly.

It really is easy to maintain a pool once you know the basics. Relying on the pool store works if you have a good pool store nearby but I have found pool stores sell chemicals and don't always take the easiest route to a well balanced pool.

Oh, I have and use test kits, but what's a person to do when the 'experts' repeatedly test your water and say you need this, that, and the kitchen sink? I'm a bit at their mercy - after all, they're the experts, right? sigh.

Anyway, for what it's worth, the CYA level is about the only one that has remained relatively level (but certainly something to keep an eye on). After I shock (Smart Shock), all levels are fine (including pH), but within 36 hours the chlorine tanks.

Water's looking good, though (for the moment). Su-weet...gonna be 99F today. 8)

I do understand. And as you see in this thread alone, there are different opinions all the way through. One says use liquid chlorine and one says never use liquid chlorine. Try more than one pool store and you'll get more than one opinion.

There are a million chemicals available for pools. IMO, most aren't needed.

Now to the disappearing chlorine. Chlorine is used up fighting the nasty stuff in the water or the sun will break it down. If your pool is crystal clear then it is probably the sun breaking it down during the day. If the pool is green or cloudy then the chlorine is probably being used up fighting something in the water.

Next time you go to the pool store, ask for a printout of the chemical balance of your pool. Post the numbers they give you here. We can give better advice knowing those numbers and knowing the type of pool and equipment you have.

I have the same problem with cloudy water. I just opened my pool a couple weeks ago, my problems started with the pool guy that pulled the cover off and dump all the debri and leaves into the pool. Next the pool water was dark green. After days of shocking the pool, I'm finally seeing cloudy water. but it has been a week of cloudy water. The pool guy told me to continue to add chlorine, sweep for two hours a day and backwash, the pool will clear up because the water at the bottom is dead water. Other than spending a lot a money at the pool store, is this good advice and when will my pool clear up?

Cloudy water

Postby New pool user » Sat 02 Aug, 2008 11:00

Good morning all. I've read your posts and I seem to be having the same issues as you. I have a 28 ft. above ground pool and use a sand filter. The water is blue, but very cloudy (can't see the bottom cloudy) There is no algae growing anywhere. Everything is clean, except for the cloudiness of the water. When we opened the pool for the summer, we had beautiful, sparkling blue water. When we opened the pool, we put all new sand in the filter, and had to replace the filter itself, as one of the arms was broken. We also put in a new pump this year since the old one burned out, so everything with the filter has to be fine....there's nothing left to replace on it. :roll:
I added clarifier to the filter yesterday, ran th filter all night and have not seen any change at all. We are not on well water.
My readings as of this morning are:
Total Hardness: 200
Free Chlorine: 10
Bromine: 20 (according to the chart, this is too high and we don't add bromine so I'm not sure where this level is coming from)
pH: 7.5
Alkalinity: 150
Cyanuric Acid: 150 (according to the chart, this is way too high also)

Any suggestions as to how to lower the bromine and CYA ?
And would the high levels of these two contribute to the cloudiness ?

Thanks!

you first need to lower your CYA level to 50-60ppm by draining some water & refilling until you get it down to this level. When CYA is to high it makes chlorine weaker to fight algae, If you use chlorine tabs in your pool stop for awhile as they have CYA in them & will cause this problem over time. Next you need to boost chlorine level above 20ppm shock level with liquide chlorine & keep it there until pool clears, so you will need to check chlorine level a couple times a day & run filter 24/7, backwashing filter when pressure rises.
