I'm still a rookie in pool care having owned my pool for a couple of months last summer and this summer. The question I have is 48 to 72 oz of liquid chlorine per day normal to maintain a 4ppm? My cya went high so I stopped using chlorine tabs. My readings are: total chlorine 4, free chlorine 3, ph 7.2, alkalinity 120, and CYA is between 50 and 100. This is my first post so please forgive for any errors.

Smithy, welcome to TFP 
How are you testing your water... which kit? Does it include a FAS-DPD powder test for FC and CC? That is the most important test to have in our opinion. You can get a good kit from TFTestkits.net Either the Taylor's K-2006 or the TF-100. They don't give you a "range" answer.. they give you an exact number. Based on drop tests not color matching. MUCH better than "Guess-Strips"

You know your CYA is high, yet you can't tell how high? So you don't know how much FC you need each day, right? Read this: [FC/CYA][/FC/CYA]
The test results you list show 1ppm CC, which means something is growing in your water chewing up that chlorine. How's your water look? I would suggest that after you get a good test kit you perform an Overnight Chlorine Loss Test (OCLT) which can tell you if you're losing chlorine to algae or something.
Overnight Chlorine Loss Test
We'll help you have a clean, sanitary pool you can enjoy. The faster we start this, the better.
