Pool Help, Please!

[megd22]

I recently bought a home and acquired an in-ground, vinyl swimming pool, with a DE filter. It is 18 x 36 and I was told from our pool place with their calculations it holds 33,000 gallons of water. Like many of the other posts, we have been having a tough time with the pool getting it clean. I had the pool ‘professionally’ opened last month, but we are still unable to use it. After spending hundreds of $$$ on pool chemicals, I came across this website and the BBB method. So to bring you up to speed, the pool is bluish-green and cloudy. We can not see to the bottom of the pool in the deep end, only about to the end of the ladder. We have added every chemical that the pool place recommended, but to no avail. I did add some bleach because when we do get the water tested our chlorine is too low. I just got the water tested about an hour ago, and now there is too much chlorine to get an accurate reading!! So I am unable to let you know what the pool levels are. I was told to come back in three to four days so they would be able to give me one. We are about to call it quits and put the cover on with all of the cleaning, vacuuming, money and time spent to see no results.

First, what can I do to combat the high chlorine levels? Is this what the baking soda would be used for? All help is greatly appreciated!!

Do you know what chemicals you've put into the pool? Not product names, but the chemicals themselves...

You really need your own test kit to care for your pool. It will pay for itself 100 times over! Since you can only buy the Taylor K-2006 online and it takes a few days to show up, go to Walmart asap and you can buy a temporary kit to use until the Taylor one is delivered. I believe they have 5 or 6 way kits for under $20 or so. You can use the 'shot glass' method to test high levels of Chlorine with the Walmart kit. Search for 'shot glass' and you can find the post that tells you how. Post the test results and what you've put in the pool and someone will help you.

Hi megd22 and welcome to the forum!!

High chlorine levels will take care of themselves with some sunlight and time, but I would first tell you to
run, not walk, away from that pool store. If they can't measure chlorine, then there's a HUGE problem. I am also suspicious of their estimation of the volume of your pool. One of the other mods has coined the term "pool-stored" to describe people like you who added what they told you to to no avail, except making them richer.

First and foremost, you need a good test kit. We recommend the Taylor K-2006. It's a bit pricey, but much less than what you've already spent on chems that don't help, and will save you its cost tenfold over this swim season. In the meantime, go to WalMart and get the 6-way kit that sells for around $15. (drop-based kit, NO STRIPS!).

Then come back and run a set of tests, then post them for:
TC, pH, TA, Ca,and CYA. We also need a list of what you've already added to the pool (ingredients, not just "shock"). Armed with that information, we can help you get it cleared up.

The pool analysis said 26,700 gallons of water. I’m not sure where I got the 33,000 from 

To date, here is what we have added to the pool in the month we have been treating it:
-Balance Pak 100--for low alkalinity
-Lo ‘N Slo--for pH adjustment
-Stabilizer 100--for low CYA levels
-Balance Pak 300--for low hardness
-Smart Shock
-Spot Kill
-Back up Algae Inhibitor
-3” chlorine tablets
-DE powder
-Polysheen Blue--for water clarity
-Balance Pak 200--for low pH
-Burn out Extreme shock
-Algaecide
-Some bleach

Luckily the former owners kept all of their testing supplies for us, so here is what I got from the 6-way tests I just did:

pH Test: 7.2

CYA test: 70ppm

Total Chlorine/Total Bromine: in the tube it turned orange and didn’t match any of the yellow on the charts. I’m assuming this is because our chlorine is really high like the pool place said. I’ll have to guy buy distilled water to do the shot glass test.

Alkalinity: I’m not sure why I did not get a reading and I did the test twice. I added the drops as directed and once I got to 11-12 drops it turned from green to a faint yellow. I added up to 30-35 drops on each test and it stayed yellow, no red.

Total Hardness: I swirled the drops around and the water turned clear, not red as indicated. I still added the titrant drops but it barely turned blue.

We’ll definitely have to order that Taylor-K kit to get more accurate readings. I’m sure this wasn’t much help to you…

Well, it looks like you have been "pool-stored." That is quite a list you have there. I have had my pool for about 10 years and I can count on one hand the number of products I have used in my pool: bleach, borax, baking soda, Polyquat 60%. That's it. Only 4. And my water always looks great and is sanitized. You don't need a bunch of stuff to keep your pool maintained. But, your pool store needs you to buy a bunch of stuff to keep their cash register full!

With a CYA of 70, you are definitely gonna need that good test kit that can measure chlorine levels higher than a cheaper kit because higher cya means higher chlorine levels needed. Your cl will need to ALWAYS stay between 5-10 or you risk an algae bloom. Your shock level will be 20ppm when needed.

No more trichlor pucks or any dichlor powder for your pool. They both contain cya in them and your level is already high. Stick with plain bleach or liquid chlorine.

Your pH is ok at 7.2 but just don't let it go any lower. If it does, add a little Borax to get it between 7.2-7.8. You do NOT need calcium in a vinyl pool. Order that kit ASAP. It will be a big help to you.

Try the shot glass dilution method and report back tomorrow with your cl level.


BTW --- Who knows how old the kit may be. Your reagents may just not be good any longer. You can check the alk and CH when you get your Taylor kit.

EDIT --- Where are my manners? I forgot to say welcome to the forum! We are glad you found us!

a couple of things:

You didn't say but I suspect your 6 way test kit is an HTH (rebranded Taylor) since you said the TA test was supposed to go from green to red and that the hardness test is a total hardness test.

The Orange color of the OTO test indicates a fairly high FC level (definitely above 10 ppm and probably closer to 20 ppm)

The TA test turning from blue to pale yellow instead of green to red is from the high chlorine. One of the indicator dyes was bleached out by the chlorine. The test is still valid if you stop when the test changes from blue to yellow. That puts your TA at about 110 to 120 ppm. It's fine for now.

the high chlorine is bleaching out the calcium test also. The colors are more like pink and pastel blue anyway under the best conditions. Your reagents could also be old. Don't lose sleep over this until you get a new test kit.

pH of 7.2 is problematic if your reagents are not old. The high chlorine levels cause pH tests to read higher than they really are and we know your chlorine is high. I suspect your pH is actually much lower than 7.2, especially if the pool was maintained on trichlor or dichlor.. We can't know for sure until the chlorine level drops to a normal range. As a safeguard I would pour a half box of borax into the skimmer. It will bring the pH up without have much impact on anything else. Test the pH the next day. If the pH still reads 7.2 with the chlorine still reading high I would add another half box. This is more of a safeguard than anything else and if it turns out that the pH was ok and it ends up a bit high it's not a big problem and one that a bit of acid will take care of in a snap!

One final thing. When you get a test kit get the Taylor K-2006 (not the K-2005). It can test chlorine levels up to about 50 ppm with a precision as small as .2 ppm! If you had it now your chlorine would not be "too much chlorine to get a reading".

[megd22]

We added a 1/2 box borax around 8 am and after testing added the other half since pH is low. We received the Taylor K-2006 kit in the mail today, so here are the results after testing with it:

pH= 7.0
cya= 80
alkalinity= 150
free chlorine= 8 (10 mL sample, 16 drops * 0.5)
when we tested for combined chlorine in step 5 after adding the 5 drops of R-0003, the sample never turned pink it stayed clear. should I add more drops until it does turn pink or this won't happen because chlorine is too high?

[sturev]

Congrats! you have no CC... That's a good thing! If after 5 drops it's not pink, your in business!

Your ph is still low, add more borax and wait about an hour and test and add more if need be.

Are you still loosing water?

[waterbear]

Your pH of 7 is the lowest you would want to be and since the FC is less than 10 there is no interference from high chlorine at the present time. I would add another half box of borax to be on the safe side.
I would also perform the bucket test to check for leaks and insepect the equipment area to make sure everything is dry there. Pay close attention to any valves and unions that might be on the equipment and the lid on the pump strainer. (anything with an O-ring for that matter).

[megd22]

We have seen some water loss, we are going to do the bucket test tonight. We did find 2 tiny holes in the liner and we used a vinyl repair kit to fix those. Also, we do have a light fixture in the deep end of the pool which seems to be pretty loose. First, can we replace the light under water? I wasn't sure if this was encased in something that allowed us to be able to do that. Also, should we just go to the pool store to get screws that would allow us to tighten that?

Since the pool is cloudy, does increasing the pH help to fix this? Sorry for all of the questions! We’re still trying to figure all of this out.
