    Shock/Clarifier

    This is my first post, I have been lurking and learning for over a month. We purchased a home last November with an in-ground pool (all known specs are in my signature). I am very open to all advice and constructive criticism. I literally know nothing and will not get offended when told what I am doing wrong. If you are reading this then I appreciate your time and any help I can get. I have had a horrible time figuring all this out and am about to give up. We have a beautiful pool and I would sure hope my family can still get some use out of it this summer.

    I will try to keep this as short as possible but it will be fairly lengthy to give the background needed to explain my situation.

    We purchased the home from an older couple who paid a pool service to do EVERYTHING for them. They had literally no knowledge to pass nor any advice what so ever about maintenance/cleaning/operation of equipment. So, around the beginning of May I had a "pool company" come open my pool. Nice guy, but he literally wasn't qualified to do much more than take the cover off. He took the cover off and couldn't get the pump to prime. Three trips later and after a pump rebuild that I am now certain was unneeded we force fed the pump water from the strainer and got it flowing. He threw a massive amount of "shock" in the pool and told me in 2-3 days it would "drop" and I would be able to see the bottom. At that point I was to vacuum and the pool would be ready to go. 5 days later the pool was still a frog pond. Twice in that time the pump lost prime in the middle of the night, eventually it lost prime and I didn't have time to mess with it and the pool set for a week or 10 days.

    Sometime in early June I got the pump running well and took a sample to the pool store. They sold me a bottle of algaecide and a bucket of shock, told me to dump it all in and bring them a sample in 3 days. I dumped the $90 worth of who knows what and waited. The morning of the third day I went outside and the pump motor was completely gone.

    After some research I ordered a Pentair Superflo 1.5 HP pump and installed it. Somewhere during this period of downtime I found this site and started reading. I knew I was done with the pool stores and this forum would be my only friend when it came to getting this pool running. There has been a lot of hurrying up and waiting since then. My pool looked worse than the pond in our pasture. There were dozens of full grown bull frogs, toads and I even pulled a small copper head out of the skimmer one morning. I knew I needed a test kit to even begin, while I waited on it I let my pump run and filtered the water while I waited. When the kit showed up (Taylor K-2006) I found that I had literally no CYA. Another 2 day wait for the stabilizer and then around a week wait for socks of CYA to dissolve.

    On July 18th I was ready. CYA 35, PH 7.2. I started my slam with a FC goal of 12 per the chart. I started at 10 AM or so and tested and added chlorine on the hour for the first 6 hours. I then went to 2 hour increments until 10 pm. I have been testing and adding at roughly 8 am and 8 pm since. The pool has gotten a lot better, but I have hit a wall. Today is day 10 and the pool has looked the same since day 5 or so. The muddy color is gone, there are no creatures left living in it, but the pool will not clear. When I take my samples at 12-18 inches each day I can see about as far down as my hand. I brush daily, and keep my filter flushed. I have never once vacuumed the pool, I keep waiting hoping to see the bottom. Having never vacuumed before I wouldn't know where to start without some visibility.

    Day 1



    Day 3



    Day 5 - It has looked like this since and we are at day 10 of the slam. Checking morning and night and bringing up to 12 each time.

    So....what's my next step? Am I on the right track? I have currently used (48) 64 ounce bottles of bleach and I bought another 30 today. I feel like I have hit a wall and the pool should be getting more clear.
    So sorry to hear about your troubles when my pool gets cloudy I use clarifier to fix it. You sprinkle it in while the filter runs and let it go about an hour. Then, shut off the filter and wait 24 hrs. When I do this, 24 hours later the water is clear and there will be brown particles at the bottom of the pool that need to be vacuumed out, vacuuming to waste ideally. You can vacuum by attaching a hose to the intake on your skimmer box and getting a pole with a vacuum head attachment from a pool store.

    For a frame of reference, I put about 2 gallons of liquid shock in my pool per week, and have a floater with chlorine tablets in it that I refill as needed. So don't fear, you won't need to spend that much on bleach once you have this pool under control! I have never put bleach in the pool so am not sure how that compares to liquid shock.


    Mod note: This is not how TFP recommends killing algae or clearing up a pool. Here is the process we recommend, SLAM, pooldv

    Re: New guy - first post - I need help if this pool is getting used before winter

    Sorry but I don't see in your signature or in your posts what kind of filtration you are using? Your pool actually isn't far off as you think...the cloudiness is from all the dead algae. Now we need to determine why it's not being filtered out....that's what's going to clear your pool.

    Sorry but you're breaking about every guideline for treating a pool....we do not advocate the use of tabs or shock...both contribute to increasing levels of CYA which eventually will leave your pool unmanageable without water drain. And while there is sometimes a place and time for clarifier it's rare and certainly not to filter algae.

    Re: Shock/Clarifier

    Have you used a pool rake and skimmer to remove all the organic debris lurking at the bottom? Just clearing the stuff that makes its way to the skimmer leaves a lot of stuff for the chlorine to eat through while the algae has a banquet.
