Sometimes you can find stabilizer at Walmart. It may be labeled as conditioner. If the ingredient is cyanuric or isocyanuric acid, it is the right stuff.

When I buy it at WalMart, it's usually in the section with the spa chemicals.

If you need to get it from Amazon, here's the link:

Thanks guys I added a gallon of bleach last night didn't take a reading but it usually gets it up to shock level. Went out this morning tested and had zero chlorine so added another gallon after I brushed. Brushing did kick up a darker green dust . Went out an hour later and chlorine was at shock level 10 on my hth 6 way test, ph was 7.2. Pool is now a lighter green. I did add a dose of clarifier last night per Bens suggestion. I'll check out Walmart for the stabilizer. I also switch out the cartridges once a day and hose them off so I keep the water pressure up and have the filter on 24/7. Thanks and have a great holiday!! I'll post again tommorrow hope the pool clears up for my pool party on the 9th or it will be a dry day lol.

Which cartridges do you have? A, B, or C?

I'm asking, because I'm going to suggest you replace them with Unicel cartridges. The Intex OEM cartridges do NOT remove algae well. In fact, if you have algae, you'd be better off REMOVING the cartridges for now, till all the algae is dead. Leave the pump on, to circulate the water.

By the way, in a 13,000 gallon pool, one gallon of 6% bleach is not going to get you to shock level. It will only add a little less than 5ppm of chlorine.

Watermon,

How high should I go? After I add the gallon the reading goes to the bright yellow so according to my kit 5-10. If I go above that I don't get a reading so I have to order the Taylor kit . If you can tell me how high and how much bleach to add I'd appreciate it. Thanks

If your CYA is 0, then your shock level is 12-15 ppm. In your pool, each gallon of 6% bleach will raise your FC by about 4.6 ppm, so 2.6 gallons would get you from chlorine of zero to chlorine of 12 ppm. Until you order the Taylor kit, you can force your kit to read higher levels of chlorine by dilution, as described here http://www.poolforum.com/pf2/forumdi...ater-Chemistry. It's not as exact as the Taylor kit, by any means, but it's a decent ballpark.

I have the B cartridges. I bought 2 new ones from Walmart and when I got them home they were quite a bit smaller didn't realize that until I unpacked some pool stuff and found 2 old ones from last season.I was wondering why I had slow water pressure and once I put the right size in I had plenty. I went to Walmart today and no stabilizer . I checked the B cartridges and saw that they were smaller than what I had at home.I'm guessing that Walmart's supply is either mis marked or just not manufactured correctly. The old cartridges were from Walmart so must be a new thing this year. I'll order the new ones from Amazon tonight along with the skimmer sock and the stabilizer. Lost all the chlorine from this morning was at zero again after being bright yellow this morning when I added more bleach. I'll take the cartridge out and just run the filter without. Thanks again for your help.
