    so, we can finally see the bottom of the pool except in the very deep end...there are lights in the pool that I didn't know were there haha. In any case, I don't understand why putting in the amount of chemicals that I am is not getting me the correct increase in ppm. For example...I've put in almost 4 pounds of cya...still not registering on the test -- and I am sure I am doing it right. ALSO, when I have put in a LOT and I mean a LOT of bleach (20 gallons in 2 days) the highest I have gotten on total Cl is 4-5 and FC is 3-5...it sticks around for a bit but based on calculations it should be getting 10ppm on the chlorine when I add in 182 fl oz x 2 of walmart brand unscented bleach -- instead I'm getting only about 3-4 ppm -- I've thought it was 16k gallons(pool installer said this based on freeform they use a conversion) but the pool calculator (3.5 ft deep shallow end, 5.5 ft deep end) 18x36 free form...pool calculator gives is 21000 or so gallons based on rectangle shape ... Any further advice there?

    When you have a sludgy pool, you've got all sorts of active biological processes going on. Until your sludge is 100% dead -- and it doesn't sound like that's happened yet -- it's impossible to predict what will happen when you add chemicals, because there's no telling what the sludge will do. For example, the right kind of sludge will eat your CYA (literally) and poop out (pretty much literally) ammonia -- which consumes HUGE amounts of chlorine.

    Beyond that, it appears you are still using 'guess strips' , which means neither you nor I know what ANY of your readings are, really.

    combo of guess strips(just to see if we are getting any FC readings) and drop tests for TC, pH, cya, TA etc...hopefully amato industries will ship soon!!!

    That's the best use of 'guess strips' -- to get a very rough idea of what's in the pool!

    It's interesting that the installer was a relatively neat plumber, but had no idea what was and was not appropriate equipment.

    You have a tiny AG pool filter, with an exceedingly shallow sand bed coupled with an 80 GPM pool pump. There are so many things wrong with this installation, it's hard to know where to begin!

    Here's a list to start with:

    #1 - Replace the Hayward CL200 with a Rainbow 320 OR with floaters.
    #2 - Discard the filter and replace with a Pentair TR24 and rework the Jandy with a smaller seal / impeller / diffuser.
    OR
    #2 - Discard the filter and replace with a Pentair TR30.

    [ I was being stupid: I meant the 24" Pentair TR60 or the 30" TR100, not the fictitious TR24 or TR30. -ben ]

    #3 - Header the 1.5" return and supply piping with 2" pipe, and connect all pump pad components with 2"
    #4 - Discard the useless Nature2 unit.
    #5 - Check the heater to make sure it's rated for 60 - 80 GPM, and if not, set up an appropriate bypass.
    #6 - It looks like there's another gizmo between the Nature2 unit and the heater. This should be ID'd and possibly removed.


    Also, because the flow restriction from the gizmos and the Hayward unit do NOT affect backwash flow, there's an excellent chance the over-sized pump has blown most of the sand out of the filter.

    Ugggg...not excited to drop 600-700 bucks for a new filter but I may have to...do you think if there is still sand in it that it may work until next season? Pretty easy to make the switch out otherwise? Probably could change the chlorinator without issues here soon and the piping to 2 inch asap also...the filter is just a big expense that im not sure I can afford at this point though...
    Thank u so much for all your help again
