    Don't add things to the pool that you don't get advice about first here on the forum. I don't know what "algae destroyer" is but the only algae destroyer that really works is chlorine. Please post a complete set of current water testing results. (Did you ever get a good test kit so you can test your own water?)

    Then, we'll go from there.

    Don't put the algae destroyer in, if you haven't already. I made the mistake of using that stuff in my koi pond one year. NOt only didn't it help, but it made my water very foamy and killed most of my flowering plants AND the fish, even though it advertised that it wouldn't.

    Stick with bleach.

    I would double check the stabilizer level to make sure it really is 0. If it really is 0, then either you never had any stabilizer to begin with (you would have had to add it in the forum of a powder or liquid called "balancer" or "conditioner" or "stabilizer". Either way, the active ingredient is cyanuric or isocyanuric acid.). If you never had any to begin with, then the sun is depleting your chlorine, and you need to add enough to get up to about 30 ppm. If you actually had CYA of 60 to begin with, and now truly have 0, that means the algae bloom and accompanying bacteria have broken down the CYA and now you have a mess on your hands. You really need to double check that number to help us figure out which it is. (And if you added the stabilizer, let us know that, too).

    The bleach will fix the pool IF you get the chlorine level up and KEEP IT UP as we described in earlier posts. That means keeping the kids out of it, and testing and adding more bleach 2-3 times daily or even more if possible. However, if you don't get the chlorine level up and keep it up there, you're spinning your wheels. Bleach and filtering will clear it, but only if it's done properly. Don't add any more baking soda, algaecide, or anything else but plain, unscented bleach. If you truly have 0 stabilizer, then 6 gallons of 6% bleach should take your chlorine up to 15 ppm, which is the level you need to maintain. Test 2-3 times daily (or as often as you can), and add more bleach to get back up above the 15 ppm mark. 1/2 gallon of bleach will raise your chlorine by approximately 1 ppm, so you can use that as a guide to figure out how much to use each time. If you DO still have stabilizer in the water, then you need to go up to 20 ppm and hold it there.

    With some persistence and patience, it will work--but you're gonna have to stay on top of it.

    What kind of test kit are you using. Unless you bought a good kit, you won't be able to test your own cya as many of the cheaper kits do not have this test.

    If you'll go to WalMart and buy the 6-way drop based kit they sell for around $15, it includes a CYA test and you can test it yourself. The problem with stabilizer (or any parameter) being "good", is that you don't know what they are comparing the "good" to. Stabilizer is stabilizer, and what level you have dictates what level of chlorine you have to keep in the pool to keep it clean. So without a good idea of what the stabilizer level is, you're just guessing when it comes to how much bleach to add. I would either get the other test kit and test it myself, or take your water sample to that store and one more, if possible, and have it tested again.

    ok my Wal Mart only had 6 way stripes so I got them and the pool store is still saying no stabilizer but the stripe says it is good at 100 so I have added 6 and half gallons of bleach we will see what it says in the morning..

    Are you using WalMart strips or the WalMart HTH drop test kit aylad recommended?

    I don't understand how a CYA level of 100ppm is indicated as "good"--it's far too high if it's accurate, which it probably isn't as strips are notoriously hard to read correctly.
