Deanna's swamp

[star21fish]

Hello everyone! I have been using this site for years, but never posted. I was cheap at the end of last season and did not buy a cover. Now, I have a green pool. I have been working on it for over a week. I have kept the chlorine levels high and filtered constantly. My pool is still green! I let the lady at the pool store convince me that Banish is the magic cure, but I have not been brave enough to pour it in, but right now I am so frustrated that I want to. I bought cal hyp to shock and some liquid chlorine, but nothing is working. I am ordering a good test kit from here, but right now this is what I know.

24 ft above ground vinyl liner
12,000-14,000 gallons....I'm not sure if it is 48 or 52 deep...going to measure right now.
sand filter....which I am having to backwash a lot

Hi, and welcome to the forum!!

First let me caution you that the pool did not get green overnight, and it won't clear overnight, so you need a really big dose of POPP--pool owner patience and persistence!!

Second, let me caution you not to add the Banish to the water. It will not clear up the problem, and it might even make it worse. Take it back to the pool store and get your money back, or exchange it for liquid chlorine.

While you're at the pool store, have them run a set of tests on the water (drop-based, not strips) and come post your results here. Once we have those, I know we can get you on the right track to a clean, clear pool.

BTW,have you added any stabilizer yet this season? Do you remember what your stabilizer (CYA) level was last year? What did you use for a chlorine source last year?

I want to add my welcome as well. Get us some numbers and someone will try and help. BTW --- not putting a cover on your pool over the winter is not the reason you have a green pool. I haven't covered my pool over the winter for several years and my pool is not green in the spring. (Poconos doesn't cover his either.) Just FYI.

Thanks for the voice of reason. Due to everything I have read on here, I know better, but she was a a very good saleslady. Although, she told me not to add bleach to my pool, that it would bleach my liner. I finally gave up, bought my leaf rake and brush and left.

I'm not sure they will take the Banish back, but I will try, just as soon as I am armed with photos of my clear pool.

Last year I used 12% liquid chlorine only. I may have added 1 pound of walmart shock to put some stabilizer in but I am so leary of stabilizer because of problems I had with my old pool. I did add one pack of it this year, but that is all stabilizer wise. No tabs, sticks, or stablized chlorine. My source for the liquid can get it for me for routine chlorination and weekly shocking, but not in the quantities needed to fix my current problem.

They ran tests yesterday, but they were the strips tests read by the computer. They gave me a huge list of things I needed to buy. She wanted me to buy 8 bags of some power shock they had(at $5.95 each). It was 56% available....dichlor. I bought cal hyp on Monday. I also bought, but already used 4 of the 1.42 gal jugs at walmart. I hope my rambling is understandable. I am still dipping leaves and some type of gooey sludge. It could be rotting leaves or the poor tadpoles We got the first foot of leaves out with a skimmer net. I wished I knew about a leaf rake....it is worth its weight in gold. The test she ran yesterday said I had no stablizer, but that my total alkalinity and calcium were low. I would be glad to post the numbers if you don't think they are worthless.

the numbers aren't worthless, just not near as good as a good drop based kit...
with a vinyl liner, don't worry about CH...
in my experience, low TA doesn't hurt, just makes the pH swing a little faster (mine is 40, and still haven't added MA in 2 weeks!)
The truly important numbers for most pools are pH, FC, CC, and CYA
With no stabilizer, you'll lose more chlorine to sunlight- astronomical amounts! any chlorine lost to sunlight is chlorine not cleaning your pool for you- so some stabilizer is good, just not to much! (mine is about 50)
keep pH somewhere around 7.2 - 7.6 when the chlorine is <10; it may read false high when chorine is higher...
keep FC at appropriate levels based on CYA in the best guess chart- keep at shock levels until you can hold FC overnight without loss and CC is <.5
run filter continuosly...
keep manually removing as much solid crap that you can
Your pool will clear
the rest of the chemicals you can worry about after the water is clear!

Here in Phoenix Walmart sells 10% HTH liquid chlorine in the dept. where they stock pool supplies in the summer (somewhere near the housewares dept.), I can buy as much as I need anytime. Might try them for a source, it sells for 6.97 for a 2 gallon case.

OK, just for grins, go ahead and post the numbers you got yesterday. We won't trust them implicitely, but it'll be a ballpark, anyway.

Assuming no stabilizer, use bleach (or liquid chlorine) to get your chlorine level up to 12-15 ppm and hold it there, by adding more as often as you can. (BTW, bleach and liquid chlorine are the same thing--the only difference is bleach is 5.25 or 6% strength, the LC is 10 or 12%. I'd be curious to see what the salesperson's response would be to the question," if bleach will fade my liner, why won't liquid chlorine?".) You can use the cheapo Chlorine/pH OTO test from WalMart to ballpark your chlorine (see the sticky in the "testing" forum about how to use dilution with the cheaper kits) . In a 12K gallon pool, each 3 cups of 6% bleach will raise your chlorine by about 1 ppm, just to use as a guide. If you can attain and keep the 15 ppm, the pool should start to clear up, and we can help you adjust your other numbers after that.

BTW, check your pH level BEFORE you shock the pool, and post it here as well....

Sorry....I haven't been back. This was our last week of school and to say it has been insane is an understatement.
My water has zero stabilizer. I am going to put a tablet in the floater.....I know that won't add much, but I have to take baby steps after my experience with it. You wouldn't by chance know how much stabilizer each tab adds?
How much cal hyp do I need to add to bring it to 15ppm?...It is 65% available. I have been adding tons and I may be just wasting it. I ordered a good test kit from the link on here, but I just have to wait on it to get here. My ph was 7.2
2 weeks ago. Today my FC is .5 and my ph was 6.8. I know my free chlorine is way to low....like I said.....this week = insane. I added some soda ash and now I'm waiting on it to circulate so I can retest. The sun is getting off the pool so as soon as someone has a sec to tell me how much cal hyp I'm back at it again. GOOD NEWS...the pool looks so much better. I can see all the steps now, but not quite the bottom. The water is now a pretty aqua color instead of the swamp green. When I backwashed a little bit ago the water coming out was disgusting and brown, but that is good right?
I am not going back to the pool store until I have pics of a sparkling pool: ) They already have me pegged for a lunatic. I don't know everything about a pool, but I do know more than her. I do realize that liquid chlorine and bleach is the same thing. I have a front load washer and you can only put 1/3 c in the dispenser, so I put 12% in my white clothes. My washcloths smell so much better!

Believe me, I know what you mean about the school week--next week is our last but I've spent all day today in assemblies at 2 different schools, and still have a banquet to attend tonight.

Regarding cal-hypo, based on 12K gallons, each 2.5 oz should raise your Cl by approximately 1 ppm. 12 oz should raise it by 5 ppm. Not sure how much stabilizer one trichlor tab adds, but I think there's a post somewhere around here about it--I'll see if I can locate it.

The fact that the backwash water looks nasty is a good thing--that stuff came out of your pool!! Keep up the good work, and just think how it feels when you can show off pretty pool pics to your local store!

Thank you so much for responding. I just realized there was a calculator that would have told me that instead of bugging everyone on here with questions. I hope you enjoy your banquet.
