Help! Big Time!

I feel that anything that can give you even a rough idea of your conditions is better than just guessing with nothing. It's sort of an emergency deal - you do what you can do right now.

You said you have an 18x4, which is likely an Intex Easy-Set. These guys are pretty close to 18 feet in diameter at the base, and taper in something like 10 inches or a foot near the top. The waterline is about 30-something inches above the floor. I measured it once, and although I don't recall the exact dimensions, I did calculate it to be right at 6000 gallons.
One gallon of 6% bleach is 0.06 gallon of actual sodium hypochlorite. In 6000 gallons, 0.06 gallons is a ratio of 6000:0.06, or 600,000:6 or 100,000:1 or 1,000,000 to 10. That's 10 parts chlorine per million parts of water. Easiest pool math you'll ever run up on.

Two gallons of bleach will put 20 ppm into the pool. That will START killing the nasties in the pool. The nasties will fight back and consume the free chlorine in the process. You will need to keep the chlorine level high to outgun and outlast the algae and bacteria and bugs and lions and tigers and bears. Oh my. This (and loss from sunlight/UV exposure) is why you need to check your chlorine levels so that you can keep it high. You could need a few gallons for the next few days.

Oh yeah... you may want a couple of filter cartridges too. Once the algae starts dying, it'll start gunking the filter. You can rinse it off with a good stiff spray from a garden hose every couple of days to keep it going, but it'll eventually clog.

Just got back from the pool store.

TDS = 350
CYA = 70
Total Cl = 0.2
Free Cl= 0.2
ph = 6.0
Total Alkaliniity = 0
calcium Hardness = 40
Copper = 0.2
Iron = 0.2
Demand Drops =10

Let me know what i need.

Can i piggy back this thread. I had a valve problem and had to shut er down for two weeks. I just got the bottom vaccummed and the valve is now working correctly. Haven't received my taylor test kit yet, but the "evillll pool store" tested my water for me and here are the results

FC=.1
TC=.8
CC-.7
ALK=152
PH=7.7
CALCIUM=222
CYA=100
TDS=1,200

using the best guess chart, I know that I need to shock to 25 and then maintain a minimum of 8 fc and a max of 15 fc. My question is how much bleach will it take to shock to 25? My pool is 16 by 32 & holds abot 18,000.

Is there a formula to determine this?

Thanks.

No, please don't piggy-back on this thread. you may have seperate issues that will confuse this one.
Find any message by 'mwsmith2' and he has a link to a great pc based BleachCalc that'll tell you everything you need to know.

To Pool Kid...
assuming you have a 6000 gallon pool ( which would be 22712.47 liters) & a cya of 70... according to the best guess chart sticky, you need to maintain a shock level of 20ppm...
so if you are at zero right now...
with regular bleach at 5.25%... that would be 8.7 liters of bleach or basically 2.3 gallons of bleach that you need to add immediately!

watch the CL levels... you want to keep adding daily until the levels appear to remain unchanged...
shortly there after, your water should clear up

Let me get this straight if the bottle says 3 QT, how many bottles do i need to add?

I thought 4 QT = 1 gallon, so would that be 3 bottles?

[RavenNS]

1 quart = 0.25 gallons
therefore : 9.2 quarts needed
or 3.067 bottles needed

If you'll add 3 of the 3qt bottles, that will be close enough to 2.3 gallons. Keep your pump running 24/7, watch your pressure so that you can clean the cartridges as needed. Brush the pool at least once a day. The key to clearing up the green is going to be to go up to the shock level, and STAY THERE. That means testing 2-3 times daily and adding whatever amount of bleach you need to get back up to the 20 ppm. If you just shock it once and let it come back down, the pool will not clear. You need to maintain the 20 ppm until the pool turns to cloudy blue, then you can slowly let your Cl drift back down, but with your CYA that high, you never want it to go below 5 ppm, to keep it from turning green again.

Youngblood, please start a new thread with your questions, if you don't already have the answers, and somebody can help you out!

My Walmart dose not sell anymore test kits

Plus The OTO test kit, They Stoped selling it at my pool store also!

Any other way?
