    Pool renovation, advice please!

    Hello everyone! I am Alan. I have a 1989 24x48 fox vinyl liner pool, 8ft deep end and 3.5 shallow end. I have been told the pool is 44,000 gallons by one company and 47,000 by another. The plumbing is all 1.5 inch pvc. On the suction side there are 2 skimmers and one main drain. On the return: 2 pipes go out and supply 2 stair jets and 1 in each corner of the shallow end wall. I am planning a renovation in late Sept(concrete is in very bad shape and I need a new liner). While I have the pool deck gone and liner out. Should I make changes? I have to keep my pump on 24/7 to keep my pool clear and clean. I have a 500lb sand filter and 1.5hp pump(20ft from a corner of the pool). What should I do to make this pool more efficient? Go to 2inch piping from skimmers to pump and add more returns or 2 inch piping for returns also? Any advice would be greatly appreciated!
    Any other suggestions to help renovation go better or add something important while everything is apart please share.

    Thanks,
    Alan

    Generally one or two turns of water a day will keep the pool clean/clear if the water chemistry is right, so before you start thinking about major changes how about we look into the chemestry. Here are the normal starting questions:

    What are you testing with?

    What are your latest test results?
    FC
    CC
    TA
    pH
    CYA

    How do you sanitize (pucks/shock, liquid chlorine, Baqua, somethin else)?

    Thanks for your reply. I get my water tested at a local pool store. For sanitizing I use an offline chlorinator that I keep on number 5 on a scale 0-7-full. I also use liquid chlorine twice a week. My last test results were:
    Alkalinity -100
    PH -7.3
    Calcium Hardness -142
    Total chlorine -2.5
    Free chlorine -1.3
    Chlorine stab -45

    Your answers confirm my suspicion, your issues are chemistry not mechanical.

    If you have read around here much you have probably seen that not much credence is given to pool store testing. While you would think that a "professional" would be the best, unfortunately in most cases it is quite the opposite. Between employees who blindly trust the word of chemical sales representatives and high school kids working in the pool store for the summer you end up with poor results from their testing.

    You will find differences between the pool care taught here and what most pool stores tell people to do. The thing most stores overlook is the relationship between Free Chlorine (FC) & CYA (also known as stabilizer). As the stabilizer level goes up the amount of FC needs to go up proportionality. Following the TFP methods with a CYA (listed on your form as "Chlorine stab") level of 45 the absolute minimum FC you should have in your pool is 4ppm and you should target 6ppm. Seeing that your FC is 1.3 and you have a Combined Chlorine (CC) of 1.2 I'm willing to bet that you have an algae bloom just waiting to happen. As you are adding chlorine you are killing some of the algae and thus making your water cloudy & dull.

    The choice will be yours as to weather you follow our methods or continue to follow the pool store methods. The one thing I do know is not to try to mix pool store advice and TFPC advice. It won't work!

    If you want to follow our methods you will need to pick up one of the recommended test kits. To effectively practice the TFPC methods, the FAS/DPD chlorine test is essential. All the kits on the list contain that test while very few other kits do. The kits sold at the pool store generally won't won't cut it, but be careful pool store employees are known to say “it's the same thing”. Generally it's not!

    To follow the pool care methods taught here you need to arm yourself with the knowledge and tools necessary to care for your pool.

    The knowledge is condensed in the Pool School link at the top of every page. It is a great community here, but we do ask that you read and try to understand the information being taught. Questions are always welcome and folks will try to direct you and teach you the methods.

    The tools are not limited to the brushes, vacuum hoses and other stuff you use around the pool, but include the most important item - one of the recommended test kits I listed above.Think of it this way, do you see a doctor blindly prescribing drugs without seeing the patient or having tests run? Here at TFP we are going to ask for photos so we can see the condition of the water and are going to ask for a full set of test results.

    Right now I know you need to conduct a SLAM to kill what is in your water. SLAM is a continuous process, not a one night addition of chlorine that continues until verified testing (yours, not the pool store) shows that nothing is living in the water.

    What is the source or the chlorine in your "offline chlorinator"? Tabs/pucks?

    So, welcome to TFP!!

    I will definitely use this new way! Thanks for all the great important information. I use tabs in the chlorinator. So you think I have enough suction and return volume? Do you think I could cut back the length of time the pump is on once I get it all balanced out?

    Yes, I do. I only run mine about 6 hours a day, but a couple of those hours are more for the sound of the waterfall.

    You need to get chlorine in that pool now. But you also need to get rid of those pucks and transition to liquid chlorine. Your pool store measured CYA of 45 is probably much higher. With high CYA comes the need for higher free chlorine levels, a connection the pool store recommendations do not address.

    So for now,

    *Get chlorine in pool

    *Order test kit

    *Read Pool School while you wait for test kit delivery.

    *SLAM your pool
