hi all back again . have some green in pool

[airraid1999]

just took cover off and was wanting to see clear water as usual but it was cloudy and either had dirt or start green algae on bottom could see bottom but when brushed it it was cloud of dirt or algae what next? i used Taylor kit but with work i just uncovered pool used stick all look great except chlorine and it was non exists so put on 2 gal of bleach will do full opening Tuesday with firing up pump and all just wanted to get a start on this problem

[aylad]

You probably have a bit of algae starting up, since the winter in many places was so much warmer than normal. Run a set of tests, post the results here, and we'll help you get it going. Without your pump running, there's not much you can do to clear up the algae, so get it running as soon as you can, tell us your CYA level, and we'll help you figure out how much bleach to add to get it clear. :)

i got pool all filled and pump started up today added a gal of bleach will check #s in morning after it runs all night will post #s as of this afternoon it was just cloudy very little if any green just a cloudy blue will test water tomorrow cant see bottom this is first time since i had pool (6 years) that i opened and wasn't clear.

[airraid1999]

did water test with taylor kit numbers are as
ph-7.4
fc-4.2
cc-2.2
ta-110
cya-60
temp-80-85 (cold) also need more regets of o871and o-870

[aylad]

Your chlorine level is too low for your CYA level, so that and your CC indicates that you need to shock the pool. With a CYA of 60, your shock level is 20 ppm of chlorine. You need to get it to 20 and hold it there as consistently as possible until you can test at night and again in the morning before the sun hits the pool and lose 1 ppm chlorine or less in that time....and until the pool clears. I suggest that you use bleach for that, since dichlor is going to raise your CYA more, which I don't think you want to do at this point. Do you know your pool's volume?

[airraid1999]

21 ft round 54" tall i think its 11000 gal. i look at last years reading and never really had cc reading and fc is way to low am i correct in saying that cc should be 0.5 or less?

[airraid1999]

got these # this morning before sun hit pool
fc-3.8
cc-0.8
ph-7.4
ta-100
cya-60
temp -cold very cold
water still cloudy can see brush in bottom but that's it I think allot of debris came off winter cover as when I moved it again allot of dusty material came off and could see where it was breaking up (3 years old) but warranty said 7 years go figure

[BigDave]

You need to add 3 gallons of 6% bleach to get up to your shock value of 20ppm FC. Run filter with pump on low 24/7, backwash as necessary (when pressure climbs 8psi or so over clean). Test as often as you can and add bleach as necessary to bring FC back to shock value. Brush the pool after adding bleach.

As you report 3.8 and 0.8 , I presume you're using the 25ml sample when testing chlorine. You're reagents will last much longer if you use the 10ml sample (remember to multiply by 0.5).

BBB for clearing a dirty pool:
Bleach - Bleach - Bleach and Brush - Brush - Brush

[airraid1999]

yes using 25ml but was tring to get exact #s till i get control of water

[BigDave]

Don't need accuracy, just reliability to control the process of cleaning up your pool. However, if you run out of reagents and have to wait for delivery you won't know what's going on to any level of accuracy.

[Watermom]

And, to answer one of your questions from one of the posts you wrote earlier, you do want the CC to be no greater than 0.5ppm.

[airraid1999]

New #s today lmk if all looks good losing some cya?
Temp=86
fc-11.5
cc-0.5
ph-7.3
ta-110
cya-45 test take after a full sun day very hot!
C hardness-200
s index- -0.2

[CarlD]

This looks just like another thread....Is this a duplicate?

Carl

Follow up: Yes, it is a dup. I have closed the other thread. Please do not post the same problem as two different threads. We WILL see it.

[airraid1999]

Ok sorry so what about #s? Didnt think this should be in this thread that's why i asked in the other?

[Watermom]

How does the pool look? Your numbers look pretty good but you still do have some CC. As far as losing CYA, probably not. That test is so subjective that it is hard to get an exact number.

[airraid1999]

Pool looks great just concerned about the cya loss and 1 mod said looks like i just shocked but i didn't those #s was after a full day of sun been checking in morning and evening and only fc and cya show slight movement the cc is very little but its there

[Watermom]

See how much chlorine loss you have overnight. If you lose no more than 1 ppm of chlorine from sundown one evening until within 2 hours of sunrise the next day, and have no more than 0.5ppm of CC, then you are probably ok.

[airraid1999]

#s virtually same still have slight cc ?

[Watermom]

Hold the chlorine high one more day. If you still have no greater than 1ppm of chlorine loss overnight and if the CC is still no greater than 0.5 and if the water looks good, then let the chlorine drift down and keep it within the correct range based on your CYA.

[airraid1999]

new #s and really worried about fc and cya????
fc-12.5
cc-0.5
ph-7.2
ta-100
cya-25 what to bring this up?
temp-87 what to do about low cya? water looks great just don't understand losing cya? using triclor tabs in floater 1 every 3-4 days??? also should i be worried of fc amount and cc is very minimal just checked at 8:00 p.m.

[aylad]

What's bothering you about the FC? If you're concerned that it's too high, it will drift down on its own. Reading back through the thread, it doesn't appear that you're losing much in the way of FC, and your CC is less than 1.0, so I'd say you're in pretty good shape.

If you want to bring the CYA up, you can either continue using tabs, which will gradually increase it, or if you want it higher now, you can add granular CYA either in an old sock hung in front of a return or by adding to your skimmer and letting it dissolve on your filter. Generally, the only way to lose it is through water loss--backwashing, splashout, etc. HOwever, it is a very subjective test, so unless you're doing it exactly the same way every time, then a 20 ppm difference is reasonable from one test to the other.

[airraid1999]

i was under impression that my fc readings was way high? am i wrong? and the cya has gradually drifted down daily but again the water is sparkling clear just look at last years #s and fc is allot higher than those if they are not high please let me know .
what is ideal readings? and yes i consider that i am doing it very close if not exactly the same each and every time

[aylad]

Your ideal readings for chlorine are determined by your CYA level...see the link in my sig for the "best guess chlorine chart" for more information there. With a CYA around 30 or so ppm, a FC of 12.5 is a little high, but you can swim in it--I just wouldn't wear a brand new bathing suit. And, in a day or so, that level will have dropped down closer to the "recommended ranges" for chlorine for that CYA. But I certainly wouldn't panic over it......

[airraid1999]

will run another test in morning to see if cya rise at night just am not used to having high fc that's all i have grand kids that have bad allergies and we went through a time last year that there eyes bothered them but i really don't think it was chlorine? i worry about them that's all and since school is out they will be over more just wanted to get ideal readings before they come over daily thanks for everyone's help!!!!

[aylad]

If you haven't added any more CYA, then it's not going to rise overnight--save the reagent until you've added some CYA, and then give it a few days to dissolve before testing for it. The FC will not stay that high for very long, with a low CYA. One or two days of sun should bring it down substantially (in my pool, it would only take one day!! ). When eyes are bothered, it's usually because the pH is too high or too low, or because the pool has lots of CC due to inadequate chlorination. A properly chlorinated pool shouldn't be hard on the eyes.

[airraid1999]

that's what i was told last years the ph should be more of issue than chlorine thanks will wait and check again in a day or so would you suggest adding stabilizer? never really had a cc problem

[aylad]

the ph should be more of issue than chlorine

The pH is not necessarily more, or less, an issue than the chlorine. Get the pH in the 7.0-7.8 range, and as long as it stays there, you're fine. The chlorine, however, will need closer attention because if it gets too low, you'll end up with a green pool.

Also, the stabilizer doesn't really have anything to do with CC....the CC is just chlorine that's engaged with fighting "goo" in the water. The stabilizer protects your chlorine from being consumed by the sun. If you have an acceptable amount of chlorine loss during the day (2-3 ppm?), and you're able to chlorinate your pool on a daily basis, then leave the stabilizer alone. HOwever, if you are losing too much chlorine to the sun, or need to chlorinate your pool less often then daily, then raising the CYA can help with that. Really, it's just personal preference. The important thing to remember, though, is that the amount of chlorine you must maintain is dependent on your CYA level. (Repeating my advice to check out the chart I referenced above).

[airraid1999]

morning #s after a backwash last night
fc-11.8 did the 25 ml sample i got plenty of reagent also plenty for cya
cc-0.0
ph-7.0
ta-110
cya-35
temp-88

[aylad]

I'd go swimming :) :cool:

[airraid1999]

again thanks too all!!!!

[Watermom]

Add a half a box of Borax slowly to the skimmer while the pump is running. Retest it several hours later and add more if needed. It's ok at 7.0 but no lower. As long as you are 7.2-7.8, you are fine. Other than this, I agree with Jan. Time to swim.

[airraid1999]

i did this morning added half a box will check again next day or 2 thanks
