Walmart chlorine vs Chlorinator

[PoolDoc]

Is it ok to use the liquid chlorine with the automatic chlorinator?

You can use bleach (aka 'liquid chlorine') with an automatic chlorinator --but don't pour it through the skimmer.

why is chlorine not holding? is it because the other chemicals are off?

Probably.

How much liquid chlorine do I use and do I spread it over the deep end or in skimmer in this case?

A 20x40 vinyl is usually around 30,000 gallons, with a PF of 4. Since 6% bleach is equivalent to 1/2 lb of 100% chlorine gas, 1 gallon will add about 2 ppm of chlorine to your pool (4 x 0.5). So, while you are having problems, adding 3 gallons (6 ppm) of bleach to your pool each evening will probably keep you out of trouble. Just pour it in to the deep end, when the pump is running.

Meanwhile, read the test kit info page (link in my sig) and get EITHER an HTH 6-way drops kit (no strips!) if your Walmart happens to have it, or a cheap OTO (yellow drops) kit. Then tell us what your pH and chlorine level are. If you get the 6-way, tell us what your CYA level is.

FYI -- Those tabs are trichlor and they are very acidic and drive pH down.

I took it the store for testing. Cya is 75 ch was .5 ph 7 alkalinity 80 we had high phosphate How should we fix.? Thanks

Don't worry about the phosphate level, it's not important at this point. Re-read the advice that Pooldoc posted above, and follow those steps, then we can help you go from there.

one more question before starting to dump chlorine tonight. what about the Ph level, should I do anything to increase that first? or do I need to wait? I have baking soda tabs I found at walmart that go into a floater that I have in the pool to help the alkalinity stay where it needs to be.
Thanks again

Probably should wait until you get a test kit to mess around with anything other than adding bleach...borax is what is advised here to raise ph.

Please fill in your information in the following chart. It makes it much easier to help. Also, if you will make a signature with your pool specs in it, please. (See link in my signature below.)

It's much easier to answer your questions, when we know something about your pool. We often 'waste' the first few posts back and forth collecting information. So, please complete our new Pool Chart form -- it takes about 30 seconds, but will save much more than that.

By the way, unless there is some product out there that I have never heard of, those tabs you saw were probably not baking soda but more likely a stabilized form of chlorine called Trichlor which add chlorine and CYA (stabilizer) at the same time.
